Bethune introduces the DB28xs Sea Tourbillon as a continuation of its 21st-century horological mission<\/li>\n<li>The timepiece features a random guilloch\u00e9 blued titanium dial that captures the fragmenting light of the deep ocean<\/li>\n<li>A redesigned 30-second tourbillon weighs just 0.18 grams while operating at a high frequency of 36,000 vph<\/li>\n<\/ul>\n<p>The De Bethune DB28xs \u201cSea Tourbillon\u201d represents a rigorous technical exercise in downsizing without compromising mechanical complexity. Centered around the Calibre DB2009V7, this release showcases the brand\u2019s ability to fuse high-frequency precision with a unique \u201cexoskeleton\u201d architecture, all while encased in a mirror-polished titanium shell that prioritizes ergonomic comfort.<\/p>\n<p>Technically, the DB28xs \u201cSea Tourbillon\u201d is defined by its redesigned tourbillon cage, which operates on a triptych of high frequency, rapid rotation, and significantly reduced weight. Comprising 63 individual components, the entire titanium frame weighs a mere 0.18 grams. This ultra-lightweight construction allows the tourbillon to complete a full rotation in just 30 seconds while maintaining a frequency of 36,000 vibrations per hour. Founder Denis Flageollet notes that this specific exoskeleton structure is not only lighter than traditional three-pillar cages but also offers enough flexibility to act as a natural shock absorber.\n<\/p>\n<p>The aesthetic and functional construction of the dial is equally advanced, featuring a random guilloch\u00e9 pattern executed on blued titanium to mimic the fragmenting light of deep-sea depths. Beneath the surface, the movement is built to withstand modern wearing conditions, utilizing a silicon escape-wheel and a balance-spring with a flat terminal curve. To ensure steady energy transmission, the watch utilizes a self-regulating twin barrel, which guarantees a power reserve exceeding five days. The exterior is finished in mirror-polished Grade 5 titanium, utilizing the signature DB28 floating lugs to ensure the smaller \u201cxs\u201d proportions remain perfectly balanced on the wrist.\n<\/p>\n<p>Denis Flageollet\u2019s pursuit of \u201c21st Century Horology\u201d has long positioned De Bethune at the vanguard of independent watchmaking. The DB28xs \u201cSea Tourbillon\u201d is the latest evolution of this mission, bringing the manufacture\u2019s patented floating lugs and mirror-polished titanium to a more intimate, wearable scale. Historically, the DB28 silhouette has served as De Bethune\u2019s primary canvas for aesthetic innovation, known for its space-age architecture and ergonomic lugs that adapt to the wearer\u2019s wrist. By applying this complex engineering to the \u201cxs\u201d platform, the manufacture maintains its \u201cStar Trek\u201d sleekness while answering the modern call for refined proportions.<\/p>\n<div class=\"show-article\">\n<p>                                                            Read Full Article<\/p><\/div>\n<\/div>\n<footer>\n<div class=\"related-stories-main-wrapper\">\n<h3>Related Stories<\/h3>\n<div class=\"stories-container\" data-layer-list-name=\"related_stories\" data-layer-list-offset=\"0\" data-layer-list-child-selector=\".story-item\">\n<div class=\"story-item\" data-layer-item-id=\"6709994\" data-layer-item-blog-id=\"1\" data-layer-item-type=\"post\"><span>&gt;<\/span>Jacob Elordi Is Officially the New Face of Bleu de Chanel\n                                                                        <\/div>\n<div class=\"story-item\" data-layer-item-id=\"6709462\" data-layer-item-blog-id=\"1\" data-layer-item-type=\"post\"><span>&gt;<\/span>A Masterpiece Chessboard and Pixel Art Diamonds: Inside Chanel\u2019s Ultra-Exclusive &#8220;Coco Game&#8221; Capsule\n                                                                        <\/div>\n<div class=\"story-item\" data-layer-item-id=\"6710122\" data-layer-item-blog-id=\"1\" data-layer-item-type=\"post\"><span>&gt;<\/span>Swatch\u2019s Latest Recreational Dive Watches Are Made From Bioceramic and Biosourced Materials\n                                                                        <\/div>\n<\/div>\n<\/div>\n<div class=\"article-email-signup-wrapper impression-tracker\">\n<h3>We got you covered.

Bethune introduces the DB28xs Sea Tourbillon as a continuation of its 21st-century horological mission<\/li>\n<li>The timepiece features a random guilloch\u00e9 blued titanium dial that captures the fragmenting light of the deep ocean<\/li>\n<li>A redesigned 30-second tourbillon weighs just 0.18 grams while operating at a high frequency of 36,000 vph<\/li>\n<\/ul>\n<p>The De Bethune DB28xs \u201cSea Tourbillon\u201d represents a rigorous technical exercise in downsizing without compromising mechanical complexity. Centered around the Calibre DB2009V7, this release showcases the brand\u2019s ability to fuse high-frequency precision with a unique \u201cexoskeleton\u201d architecture, all while encased in a mirror-polished titanium shell that prioritizes ergonomic comfort.<\/p>\n<p>Technically, the DB28xs \u201cSea Tourbillon\u201d is defined by its redesigned tourbillon cage, which operates on a triptych of high frequency, rapid rotation, and significantly reduced weight. Comprising 63 individual components, the entire titanium frame weighs a mere 0.18 grams. This ultra-lightweight construction allows the tourbillon to complete a full rotation in just 30 seconds while maintaining a frequency of 36,000 vibrations per hour. Founder Denis Flageollet notes that this specific exoskeleton structure is not only lighter than traditional three-pillar cages but also offers enough flexibility to act as a natural shock absorber.\n<\/p>\n<p>The aesthetic and functional construction of the dial is equally advanced, featuring a random guilloch\u00e9 pattern executed on blued titanium to mimic the fragmenting light of deep-sea depths. Beneath the surface, the movement is built to withstand modern wearing conditions, utilizing a silicon escape-wheel and a balance-spring with a flat terminal curve. To ensure steady energy transmission, the watch utilizes a self-regulating twin barrel, which guarantees a power reserve exceeding five days. The exterior is finished in mirror-polished Grade 5 titanium, utilizing the signature DB28 floating lugs to ensure the smaller \u201cxs\u201d proportions remain perfectly balanced on the wrist.\n<\/p>\n<p>Denis Flageollet\u2019s pursuit of \u201c21st Century Horology\u201d has long positioned De Bethune at the vanguard of independent watchmaking. The DB28xs \u201cSea Tourbillon\u201d is the latest evolution of this mission, bringing the manufacture\u2019s patented floating lugs and mirror-polished titanium to a more intimate, wearable scale. Historically, the DB28 silhouette has served as De Bethune\u2019s primary canvas for aesthetic innovation, known for its space-age architecture and ergonomic lugs that adapt to the wearer\u2019s wrist. By applying this complex engineering to the \u201cxs\u201d platform, the manufacture maintains its \u201cStar Trek\u201d sleekness while answering the modern call for refined proportions.<\/p>\n<div class=\"show-article\">\n<p>                                                            Read Full Article<\/p><\/div>\n<\/div>\n<footer>\n<div class=\"related-stories-main-wrapper\">\n<h3>Related Stories<\/h3>\n<div class=\"stories-container\" data-layer-list-name=\"related_stories\" data-layer-list-offset=\"0\" data-layer-list-child-selector=\".story-item\">\n<div class=\"story-item\" data-layer-item-id=\"6709994\" data-layer-item-blog-id=\"1\" data-layer-item-type=\"post\"><span>&gt;<\/span>Jacob Elordi Is Officially the New Face of Bleu de Chanel\n                                                                        <\/div>\n<div class=\"story-item\" data-layer-item-id=\"6709462\" data-layer-item-blog-id=\"1\" data-layer-item-type=\"post\"><span>&gt;<\/span>A Masterpiece Chessboard and Pixel Art Diamonds: Inside Chanel\u2019s Ultra-Exclusive &#8220;Coco Game&#8221; Capsule\n                                                                        <\/div>\n<div class=\"story-item\" data-layer-item-id=\"6710122\" data-layer-item-blog-id=\"1\" data-layer-item-type=\"post\"><span>&gt;<\/span>Swatch\u2019s Latest Recreational Dive Watches Are Made From Bioceramic and Biosourced Materials\n                                                                        <\/div>\n<\/div>\n<\/div>\n<div class=\"article-email-signup-wrapper impression-tracker\">\n<h3>We got you covered.

Bethune introduces the DB28xs Sea Tourbillon as a continuation of its 21st-century horological mission<\/li>\n<li>The timepiece features a random guilloch\u00e9 blued titanium dial that captures the fragmenting light of the deep ocean<\/li>\n<li>A redesigned 30-second tourbillon weighs just 0.18 grams while operating at a high frequency of 36,000 vph<\/li>\n<\/ul>\n<p>The De Bethune DB28xs \u201cSea Tourbillon\u201d represents a rigorous technical exercise in downsizing without compromising mechanical complexity. Centered around the Calibre DB2009V7, this release showcases the brand\u2019s ability to fuse high-frequency precision with a unique \u201cexoskeleton\u201d architecture, all while encased in a mirror-polished titanium shell that prioritizes ergonomic comfort.<\/p>\n<p>Technically, the DB28xs \u201cSea Tourbillon\u201d is defined by its redesigned tourbillon cage, which operates on a triptych of high frequency, rapid rotation, and significantly reduced weight. Comprising 63 individual components, the entire titanium frame weighs a mere 0.18 grams. This ultra-lightweight construction allows the tourbillon to complete a full rotation in just 30 seconds while maintaining a frequency of 36,000 vibrations per hour. Founder Denis Flageollet notes that this specific exoskeleton structure is not only lighter than traditional three-pillar cages but also offers enough flexibility to act as a natural shock absorber.\n<\/p>\n<p>The aesthetic and functional construction of the dial is equally advanced, featuring a random guilloch\u00e9 pattern executed on blued titanium to mimic the fragmenting light of deep-sea depths. Beneath the surface, the movement is built to withstand modern wearing conditions, utilizing a silicon escape-wheel and a balance-spring with a flat terminal curve. To ensure steady energy transmission, the watch utilizes a self-regulating twin barrel, which guarantees a power reserve exceeding five days. The exterior is finished in mirror-polished Grade 5 titanium, utilizing the signature DB28 floating lugs to ensure the smaller \u201cxs\u201d proportions remain perfectly balanced on the wrist.\n<\/p>\n<p>Denis Flageollet\u2019s pursuit of \u201c21st Century Horology\u201d has long positioned De Bethune at the vanguard of independent watchmaking. The DB28xs \u201cSea Tourbillon\u201d is the latest evolution of this mission, bringing the manufacture\u2019s patented floating lugs and mirror-polished titanium to a more intimate, wearable scale. Historically, the DB28 silhouette has served as De Bethune\u2019s primary canvas for aesthetic innovation, known for its space-age architecture and ergonomic lugs that adapt to the wearer\u2019s wrist. By applying this complex engineering to the \u201cxs\u201d platform, the manufacture maintains its \u201cStar Trek\u201d sleekness while answering the modern call for refined proportions.<\/p>\n<div class=\"show-article\">\n<p>                                                            Read Full Article<\/p><\/div>\n<\/div>\n<footer>\n<div class=\"related-stories-main-wrapper\">\n<h3>Related Stories<\/h3>\n<div class=\"stories-container\" data-layer-list-name=\"related_stories\" data-layer-list-offset=\"0\" data-layer-list-child-selector=\".story-item\">\n<div class=\"story-item\" data-layer-item-id=\"6709994\" data-layer-item-blog-id=\"1\" data-layer-item-type=\"post\"><span>&gt;<\/span>Jacob Elordi Is Officially the New Face of Bleu de Chanel\n                                                                        <\/div>\n<div class=\"story-item\" data-layer-item-id=\"6709462\" data-layer-item-blog-id=\"1\" data-layer-item-type=\"post\"><span>&gt;<\/span>A Masterpiece Chessboard and Pixel Art Diamonds: Inside Chanel\u2019s Ultra-Exclusive &#8220;Coco Game&#8221; Capsule\n                                                                        <\/div>\n<div class=\"story-item\" data-layer-item-id=\"6710122\" data-layer-item-blog-id=\"1\" data-layer-item-type=\"post\"><span>&gt;<\/span>Swatch\u2019s Latest Recreational Dive Watches Are Made From Bioceramic and Biosourced Materials\n                                                                        <\/div>\n<\/div>\n<\/div>\n<div class=\"article-email-signup-wrapper impression-tracker\">\n<h3>We got you covered.

By applying this complex engineering to the \u201cxs\u201d platform, the manufacture maintains its \u201cStar Trek\u201d sleekness while answering the modern call for refined proportions.<\/p>\n<div class=\"show-article\">\n<p>                                                            Read Full Article<\/p><\/div>\n<\/div>\n<div class=\"post-body-author d-block d-lg-none\">\n<hr class=\"sidebar-divider share-divider\">\n<h6>Text By<\/h6>\n<p><span class=\"author-name\">Sophie Caraan<\/span><\/div>\n<div class=\"post-body-credentials d-block d-lg-none\">\n<hr class=\"sidebar-divider\">\n<div class=\"credential\">\n<h6>Editor Assistant<\/h6>\n<p><span>Mai Vo<\/span><\/div>\n<\/div>\n<div class=\"post-body-share d-block d-lg-none\">\n<hr class=\"sidebar-divider\">\n<h6>Share this article<\/h6>\n<\/div>\n<div class=\"post-body-content-tags\">\n<div class=\"body collapsed\">\n<p>    De Bethunede bethune db28xs\n                                                            <\/p><\/div>\n<\/div>\n<p>[analyse_source url=&#8221;https:\/\/hypebeast.com\/2026\/4\/de-bethune-and-denis-flageollet-are-reinvigorating-maritime-horology-with-the-db28xs-sea-tourbillon&#8221;]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[analyse_image type=&#8221;featured&#8221; src=&#8221;https:\/\/image-cdn.hypb.st\/https%3A%2F%2Fhypebeast.com%2Fimage%2F2026%2F04%2F24%2FDe-Bethune-DB28xs-Sea-Tourbillon-Release-Info-tw.jpg?w=1080&amp;cbr=1&amp;q=90&amp;fit=max&#8221;] Watches Apr 24, 2026 252 Views 0\u00a0Comments Comments Save Text By Sophie Caraan Editor Assistant Mai Vo Share this article 1 of 4 De Bethune 2 of 4 De Bethune 3 of 4 De Bethune 4 of 4 De Bethune Watches Apr 24, 2026 252 Views 0\u00a0Comments Comments Save Summary De Bethune [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2],"tags":[226,39],"class_list":["post-1904033","post","type-post","status-publish","format-standard","hentry","category-politics","tag-crawlmanager","tag-hypebeast-com"],"_links":{"self":[{"href":"https:\/\/analyse.optim.biz\/index.php?rest_route=\/wp\/v2\/posts\/1904033","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/analyse.optim.biz\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/analyse.optim.biz\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/analyse.optim.biz\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/analyse.optim.biz\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=1904033"}],"version-history":[{"count":0,"href":"https:\/\/analyse.optim.biz\/index.php?rest_route=\/wp\/v2\/posts\/1904033\/revisions"}],"wp:attachment":[{"href":"https:\/\/analyse.optim.biz\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=1904033"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/analyse.optim.biz\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=1904033"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/analyse.optim.biz\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=1904033"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
