Strap for 1926 39 Stainless Steel / Opaline

The lug width of the Tudor 1926 91550-0005 is 21mm. This is the distance between the case lugs where the strap attaches. It is a specific measurement that excludes universal 20mm straps and requires dedicated straps for this particular lug width.

Alligator leather in vegetable tanning is the natural choice to emphasise the minimalist character of the 91550-0005. The fine grain and patina that develops over time create harmony with the essential dial. Alternatively, calf leather with linen texture or shell cordovan offer distinct textures with superior durability in daily wear.

To change the strap: (1) extract the spring bars using a spring bar removal tool by inserting the flat tip into the side slots; (2) remove the strap by pushing the bars towards the centre; (3) insert the pins of the new strap into the same holes and press until locked. If unfamiliar with the procedure, the Casati Milano atelier can assist with expert personnel.

Yes, any strap with a 21mm lug width is compatible with the 91550-0005. Benefits include: greater choice of materials (alligator, calf, shell cordovan, rubber), customisation options (length, colour, stitching thread), and superior artisanal quality compared to factory straps.

A natural leather strap (alligator, calf, shell cordovan) has an estimated lifespan of 3 to 7 years depending on use, climate, and care. An alligator strap in vegetable tanning ages elegantly, developing patina that increases aesthetic value. Casati Milano's warranty on artisanal straps is 18 months, but true longevity depends on maintenance.
