Strap for 1926 39 Stainless Steel / White - Diamond

The lug width of the Tudor 1926 91550-0013 is strictly 21 millimetres. This measurement is critical for correct strap fitting: a 20mm or 22mm lug width will not fit precisely. The measurement is obtained by positioning a digital calliper between the left and right shoulder of the case lug.

For the Tudor 1926, we recommend alligator or quality calf leather. Alligator offers distinctive scale texture and natural patina development over time; calf, especially vegetable-tanned, guarantees density and dignified ageing. For intensive daily use, vulcanised rubber or fabric nato resists moisture better. Choice depends on usage context and aesthetic preference.

To change the strap: 1) obtain a spring bar remover tool; 2) position the watch with the strap facing downward; 3) gently press the spring of one lug end, releasing the pin; 4) repeat from the other side; 5) remove the old strap and insert the new one, aligning the holes. Ensure the lug clicks fully into position.

Any strap with a 21mm lug width is compatible. You will find extensive choice online at milanostraps.it, with leathers in alligator, calf, shell cordovan, nato and rubber. Always verify that the strap is manufactured precisely at 21mm, not 20mm or 22mm. For advanced personalisation (stitching thread, initials, custom length), contact the Casati Milano atelier.

Durability varies by material and usage. Quality vegetable-tanned calf lasts 4-6 years in daily use; alligator may last 5-7 years owing to stronger structure; shell cordovan reaches 10+ years. Perspiration, moisture and sun exposure accelerate wear. Proper maintenance (regular cleaning, drying, annual conditioning) significantly extends strap life.
