Strap for 1815 38.5 White Gold

The lug width of the A. Lange & Söhne 1815 235.026 is 20 millimetres. This measurement is specific to the model and determines strap compatibility. Verify it by measuring the distance between the two lugs (passants) where the strap attaches to the case.

The ideal strap for the 235.026 is a natural alligator in black or grey (Himalaya), or vegetable-tanned calfskin that ages gracefully. Shell cordovan in bordeaux tone is the choice of the purist. All these materials maintain Glashütte's aesthetic equilibrium without competing with the dial.

The strap is changed by removing the pins (spring bars) that hold the strap to the case lugs. Use a specialised tool (spring bar remover) or consult a watchmaker. The pin diameter is proportioned to the 20-millimetre lug width. Casati Milano offers personalised installation service by appointment.
