De Bethune is revisiting its classics and reasserting its identity codes through the DB28, a strongly identifiable collection endowed with the signature House style features and conveying its resolutely avant-garde vision of the watchmaking art!
Mid-way between the DBS and the model developed exclusively by De Bethune for Only Watch 2009, the DB28 collection strikes the perfect balance between the know-how cultivated by the Manufacture and its horological innovations.
The design of the watch is entirely in line with existing creations by De Bethune: the dedicated shape of the case adorned with its famous crown at 12 o'clock, inspired by pocket-watches and emphasised by the spherical moon or the De Bethune tourbillon, are a set of distinctive traits characterising the contemporary aesthetic of the Manufacture. The dial serves as a window onto the movement, revealing the refined craftsmanship of the handexecuted finishes developed in the De Bethune workshops. The delta-shaped polished steel mainplate and De Bethune “stripes” are combined with a chapter ring to ensure optimal readability. The shimmering effects of the light playing across the polished and matt surfaces create a unique show visible exclusively on the wrists of a privileged few.
The wearer comfort of the DB28 stems from the surprising lightness of the case entirely made in titanium, and to the presence of “floating lugs”, a patented system that easily adjusts to the size of the wrist and its various movements. In keeping with the Belle Epoque style, the solid back of the DB28 is inspired by the hunter-type shape of pocketwatches, and also incorporates a power-reserve indicator.
The quest for perfection and beauty is the constant driving force behind the work of David Zanetta and Denis Flageollet, the artisans behind this exceptional timepiece with its pure style, of which the taut lines and slender case are the unmistakable signature of De Bethune's contemporary expression of the watchmaking art.

DB28
The DB28 is powered by Calibre DB2115 which is equipped with the latest technological innovations developed and produced within the Manufacture De Bethune. This precision is reinforced by the self-regulating twin barrel and the presence within the regulating organ of the new silicon/platinum balance wheel with a flat terminal curve protected by the triple pare-chute shockabsorbing system.
Much like what can be observed from the sky, moon phases are read off by an exclusive display system by means of a platinum and blued steel sphere revolving on its axis and which is accurate to within one day every 122 years.

DB28T
The DB28T is powered by Calibre DB 2009 a mechanical hand‐wound movement which is equipped with an ultralight 0.18 gram silicon/titanium tourbillon.
De Bethune thus undertook to rethink the tourbillon around this new wristwatch dynamic. The laws of physics are implacable: in order to compensate for the disorganised violence of wrist movements, the carriage must be as light as possible with as high a frequency as possible and a maximum rotation speed for a minimum mass and inertia. Thanks to new technologies, De Bethune has therefore created a 0.18 g silicon-titanium tourbillon in a carriage spinning once every thirty seconds at its axis, and a balance oscillating at a frequency of 36,000 vibrations per hour. This tourbillon is the lightest on the market (classic counterparts weigh four times as much) and comprises 50 parts, of which the lightest weighs less than 0.0001 grams and the “heaviest” 0.0276 grams!
TECHNICAL SPECIFICATIONS
DB28
Functions : hours – minutes- spherical moon-phase indicator at 6 o'clock – power-reserve indication – performance indicator
Movement :
Calibre DB 2115 – mechanical hand-wound
Mainplate hand-decorated and snailed, hand-chamfered and polished steel parts, De Bethune stripes
Self-regulating twin barrel*- The barrels are specifically designed to eliminate friction and efficiently transmit a maximum of energy.
Silicon/platinum balance wheel* with flat terminal curve – Its exceptional lightness enables this balance wheel to reduce mechanical friction and deliver an ideal inertia/mass ratio. The principle of the flat end curve, placed on the same level as the balance-spring, compensates for off-centering and facilitates its fastening
Triple pare-chute shock-absorbing system* reduces potential disturbances due to impacts to an absolute minimum and protects the balance-spring pivots.
Exclusive three-dimensional moon-phase indication* by means of a platinum and blued steel sphere revolving on its axis and accurate to within one day every 122 years.
Jewelling : 29 jewels
Frequency : 28,800 vibrations per hour
Power reserve : 6-day power reserve indicated on the back of the case
Case : 43 mm in diameter, made from grade 5 titanium or rose gold, 11.3 mm thick
Lugs : mobile or floating type* in grade 5 titanium with pivoting system. Their springs follow the shape of the wrist and its movements.
