Strap for Museum Collection Centenary 1894 Red Gold / Gilt / Japan

The lug width measures 18mm, a rare constructive specification that reflects the proportions of the 35mm case. This width maintains aesthetic balance between the reduced diameter and wrist attachment, preventing a more generous strap from visually oversizing the watch.

Alligator with regular texture amplifies the vintage-modern character of the 5950.31.03. If you prefer visible aging, vegetable-tanned calf develops unique patina over time. French shell cordovan offers sophisticated contrast and superior resistance, for those who know the material.

Use a spring bar tool specifically designed for watches. Position the tool on the lateral pin, apply gentle and steady pressure to extract it. Repeat on the other side. Insert the new strap by aligning the holes with the metal protrusions (the lugs), then reinsert the pins. Verify that the strap is exactly 18mm before starting.

Yes, provided they are constructed for 18mm lug width. Always verify the internal width between the pins (must be exactly 18mm) and check that the strap thickness is not excessive, to ensure smooth movement in the case attachments.

Average lifespan is 2-4 years with daily wear, depending on the material (alligator and cordovan resist longer than standard calf) and your maintenance routine. Protecting from prolonged moisture and excessive perspiration significantly extends the strap's life.
