De Bethune has a new addition to the family, the DB25 Moon Phase timepiece features a drum case which is crafted from either 18 carat rose or white gold. The case has the impressive diameter of 44.6 mm and 11.1 mm thick. The classic dial has is silvered gold with a guilloche pattern done entirely by hand. Below the 12 o'clock mark lies a window revealing the De Bethune spherical moon phase, this beautiful blue sky dotted with gold stars is nicely complemented by the flame-blued hands and markers. The moon phase itself consists of two hemispheres, one in steel and the other in platinum, which is also flame-blued by hand and rotates on its own axis. The mechanism for turning the sphere has been calculated so accurately that it will take 122 years before it requires a correction. The face is protected by a sapphire crystal with a 1800 Vickers hardness and a double anti-reflective treatment.

The DB25 Moon Phase timepiece is powered by the new DB2105si hand-wound mechanical movement which features a power reserve of up to six days. The movement contains 29 jewels and beats at a frequency of 28’800 vibrations per hour. The movement has been decorated and “colimaçonné” as well as steel chamfered and polished by hand. It has a self-adjusting double spring barrel and a silicon annular balance with flat terminal curve. The functions for the watch include hours, minutes, moon phase indication and a power reserve indicator on the back.
