Tudor
1926 91350-0011 (aka: M91350-0011)— lug 15mm

The Tudor 1926 91350-0011 features a lug width of 15 millimetres. This precise measurement reflects the proportions of the 28 mm case. To verify it, place a calliper or measuring tape within the internal lug area: you will measure exactly 15 mm. This width is less common than the 18–20 mm found on larger models, so verification is essential before purchasing an aftermarket strap.

The ideal strap depends upon your usage context. For classical elegance, we recommend alligator in brown or black, vegetable-tanned, as it ages gracefully and develops rich patina over time. For daily versatility, a grey-stone calf leather offers aesthetic flexibility. For sport without compromise, a NATO in cotton—navy blue or grey—is the solution. All straps must feature a 15 mm lug to ensure perfect compatibility.

Strap replacement is straightforward. Position your watch face-down on a soft, protective surface. Locate the lugs (the metal pins protruding from the case). Using a spring bar tool (a small lever usually supplied), gently lift one end of the internal spring mechanism, allowing it to disengage from the hole. Repeat on the other side. Remove the old strap and insert the new one by threading the central tube of the lug through the hole, then lower the spring to secure. Ensure the strap sits symmetrically.

Yes, but exclusively those featuring a 15 mm lug width. Milano Straps offers a comprehensive collection of artisanal straps in 15 mm, crafted from premium leathers—alligator, shell cordovan, calf—and customisable upon request. You may select colour, finish, embroidered initials, and stitching thread type. The Casati Milano atelier also provides in-person measuring services by appointment for a complete sartorial experience.

Longevity depends upon material and usage. An alligator strap, used daily, typically lasts 3–5 years, developing fascinating patina as it ages. Calf leather exhibits initial wear signs after 2–3 years but remains functional. Shell cordovan, being harder, may achieve 5–7 years of active life. Vegetable-tanned leather reinforces durability over time. Regular maintenance—cleaning with a damp cloth, avoiding excessive water exposure—significantly extends longevity.
