De Bethune last week launched the DB Kind of Two Tourbillon, a two-sided watch with a contemporary tourbillon dial that the wearer can flip to show a classical time-only dial.

Like other two-sided watches, the new De Bethune watch means the wearer can choose to expose one of two different dials on his or her wrist.

The contemporary side of the De Bethune DB Kind of Two Tourbillon.

One side of the 42.8mm titanium watch displays the contemporary design with multi-level elements and delta-shaped bridge for which De Bethune is identified. This dial features the brand’s distinctive central hours and minutes hands and its high-speed tourbillon and a thirty-second indication. Here however, De Bethune altered its deltoid-shaped bridge just a bit to make it perfectly symmetrical, a design meant to create a stark sense of harmony.

Classic side

On the other side of the DB Kind of Two De Bethune offers a more classical three-hand, time-only hand-guilloché dial, complete with Arabic numerals collectors might recognize from the brand’s DB8 and DB10. Note that the seconds indication on this side is centrally based, unlike the tourbillon-based seconds indication at the 6 o’clock position on the other side.

De Bethune notes that two-dial watches and clocks have a long history, starting with multi-face tower clocks and extending to similarly equipped table clocks. More recently, we’re familiar with the famed dual-dial Jaeger-LeCoultre Reverso.  Serious collectors also wear certain two-faced watches from Bovet, Cartier and others.

To devise the new dual-dial watch, De Bethune had to re-design its famed floating lug case to allow the flip-over case to pivot easily, rotate on its central axis and then to click into place securely. This operation is a simple one because the brand equipped each side of the case with a clever rotating mechanism made up of twenty-eight steel and titanium components.

Equally important is the case’s middle section, which swivels naturally and frames the case and the crown. That crown lands gracefully at either 6 o’clock or 12 o’clock, depending on which side of the DB Kind of Two Tourbillon the wearer chooses to view.

Inside the watch De Bethune’s Caliber DB2579 features patented technical flourishes well known to De Bethune devotees. These include a titanium balance with white gold inserts (optimized for temperature differences and air penetration) and a self-regulating twin barrel. For the tourbillon, De Bethune utilizes the ultra-light, 30-second titanium design it first debuted in 2008.

Price: $250,000.
