Lange 31
Ref.: 130.039F
The Lange 31 from A. Lange & Söhne is about pushing watchmaking's limits. With an insane 31-day power reserve, this 45.9mm white gold beauty is built for the long haul. The grey dial keeps things refined, while the manual-winding L034.1 movement powers the big date display and small seconds. Limited to just 100 pieces, it's a masterpiece of engineering and craftsmanship.
