Speedmaster (Non-Moonwatch) ST 176.0002— lug 18mm

The lug width of the Speedmaster ST 176.0002 is exactly 18 mm. This measurement is taken internally between the shoulders of the lugs using a digital caliper. It is essential to verify this measurement before purchasing an aftermarket strap to avoid undue tension or excessive gaps during insertion.

For the ST 176.0002, we recommend vegetable-tanned alligator, which offers an elegant balance between sportiness and refinement. Natural-grained calf represents a versatile alternative for everyday wear, while shell cordovan proves ideal for those who appreciate pronounced patina development. Natural rubber straps remain the most practical choice for summer use.

To change the strap on the ST 176.0002, you must remove the current strap by gently extracting the lug from the case lugs using a dedicated tool (or a rounded-tip micro-screwdriver). Next, insert the new 18 mm lug into the case lugs, ensuring it is perfectly aligned. If the strap is equipped with a deployant, verify that the mechanism is intact before final assembly.

Yes, the ST 176.0002 accepts any strap with an 18 mm lug width. On milanostraps.it you will find a dedicated collection of compatible artisanal straps, crafted in alligator, calf, shell cordovan and rubber, all customizable in size, initials and stitching color.

The lifespan of a leather strap depends on the material and usage. A quality artisanal alligator or calf strap has a longevity of 3-5 years with daily wear, with the possibility of extension thanks to the protective patina that develops over time. Shell cordovan, more resistant but initially stiff, can exceed 7-8 years. Casati Milano offers an 18-month warranty on all made-to-measure straps, with post-warranty maintenance and repair service.
