Datejust 41 126334-0002— lug 21mm

The lug width of the Datejust 41 126334-0002 is 21 millimetres. This measurement, taken from centre to centre of the spring bar passage, is the standard construction specification for this two-tone model. Any replacement strap must adhere precisely to this dimension to ensure mechanical compatibility and correct visual alignment.

For the Datejust 41 126334-0002 in white gold and stainless steel, we recommend alligator in cognac or hazelnut tones, which enhances the warmth of the gold. Alternatively, taurillon calf leather with vegetable tanning offers timeless elegance and develops natural patina. For sporty contexts, vulcanised rubber with leather passant maintains the formal integrity of the two-tone whilst offering gestural versatility.

Strap replacement requires a spring bar tool to extract the spring bars from the lugs. We recommend entrusting this operation to a professional watchmaker to avoid case scratches or damage to the spring bars. Casati Milano offers dedicated assistance: contact the atelier for personalised consultation by appointment.

Yes, any quality strap with 21mm lug width is mechanically compatible. However, we recommend fine crafted straps in noble materials (alligator, calf) to preserve the prestige of the two-tone. Milanostraps offers curated selections of 21mm straps; Casati Milano crafts bespoke pieces with dedicated follow-up service.

A quality strap with vegetable tanning lasts approximately 3–5 years with daily use, developing characteristic patina over time. Longevity depends on frequency of use, moisture exposure and maintenance. Casati Milano guarantees 18 months against manufacturing defects; thereafter the strap can be restored through reconditioning and partial component replacement.
