Strap for Tank Française Medio (MM) W51012Q4

The lug width of the W51012Q4 is 17 mm. This is a specific measurement for the Tank Française collection, calibrated to the geometric proportion of the 28 mm rectangular case. To verify, measure the distance between the spring bar holes using a digital calliper or consult a specialist watchmaker.

Alligator in cognac or dark brown tones is the ideal choice: the fine grain enhances the rigid geometry of the case. A noble alternative is shell cordovan, whose natural patina dialogues with the aging of yellow gold. For a more versatile option, vegetable-tanned calf leather offers elegance without excessive formality.

The spring bars of the W51012Q4 are extracted using a dedicated tool (spring bar tool). Position the watch with the lugs parallel to the table edge, insert the tool into the lower groove of the bar, apply gentle downward pressure until the bar retracts, then remove the strap. Repeat on the other side. Proceed carefully to avoid scratching the case.

Yes, provided the strap is manufactured for a 17 mm lug width. The width is not a standard NATO or military size, so always verify the product specifications. The 17mm straps from milanostraps.it are specifically designed for the Tank Française and compatible models.

A quality leather strap (alligator, shell cordovan, vegetable-tanned calf) lasts between 2 and 5 years with daily use, depending on exposure to moisture and perspiration. Alligator tends to be more durable. To extend longevity, avoid prolonged water exposure and dry the strap with a soft cloth after moisture exposure. Annual treatment with natural wax prevents premature aging.
