Strap for Speedmaster Professional Moonwatch Yellow Gold

The lug width is 20mm. This measurement is specific to the 3695.50.31 model and represents the distance between the two case lugs. All compatible straps must respect this dimension to ensure a perfect fit into the case lugs.

Dark brown alligator is the most authoritative choice, as the geometric grains visually echo the chronograph dials and the natural patina harmonizes with the warmth of 18K gold. For daily wear, vegetable-tanned calf leather in cognac tones offers sobriety and chromatic evolution over time. A navy NATO strap ensures tactical versatility without compromising formality.

The lugs on this model are solid and the attachment is via screw. Use a dedicated tool to gently unscrew the pins, ensuring the case does not experience stress. Once you have removed the old strap, insert the new one and screw the pins with uniform precision. If you lack experience, entrust the work to a professional watchmaker.

Yes, provided the width is exactly 20mm and the total length is sufficient to wrap around the wrist with the deployant clasp.

A quality alligator or calf leather strap lasts 3-5 years with daily wear, developing a desirable patina in the first year. Durability depends on perspiration, sun exposure and frequency of rotation among multiple straps. A vegetable-tanned strap ages more aesthetically than chromium-tanned or low-quality straps, adding character rather than deterioration.
