Strap for Black Bay 31 S&G - Diamond / Silver / Bracelet

The lug width of the Tudor Black Bay One 79613-0002 is precisely 16mm. This measurement represents the internal distance between the two pins (spring bars) that connect the case to the strap. It is crucial to measure this dimension accurately, as an oversized or undersized strap compromises both aesthetics and functionality. A correctly dimensioned strap must accommodate the pins without excessive play, ensuring natural rotation during wear.

For the Black Bay One 79613-0002, black alligator with vegetable tanning represents the ideal option, thanks to its characteristic grain and natural patination that harmonize with the black dial and satin-finished steel. Alternatively, European calf leather with satin grain in dark brown or burgundy tones offers daily versatility, whilst warm shell cordovan echoes the yellow gold case tones. For sportive wear, FKM rubber straps maintain a refined finish compatible with the case's sophistication.

To change the strap on the 79613-0002, remove the pins (spring bars) connecting the case to the straps. Use a dedicated spring bar tool, gently pressing one side to release the internal spring mechanism and permit extraction. Once the pins are removed, slide off the old strap and insert the new one, ensuring the lugs are dimensioned for the 16mm lug width. Reinsert the pins with gentle pressure until they are fully seated in the case.

Any strap equipped with lugs sized for a 16mm lug width is compatible with the 79613-0002. Milano Straps offers a range of straps in alligator, calf, shell cordovan, cotton NATO and FKM rubber, customisable in dimensions, colours and stitching thread. The Casati Milano atelier further provides bespoke realisation with personal hide selection, WhatsApp updates and an 18-month warranty, guaranteeing perfect fit and superior-quality materials.

The lifespan of a leather strap varies according to material and usage conditions. An alligator strap with vegetable tanning may endure 5-7 years with regular maintenance (monthly cleaning and bi-annual conditioning), developing a natural patina that enhances aesthetic value. European calf typically lasts 3-4 years, whilst shell cordovan, owing to its natural density, can exceed 7-8 years. Prolonged exposure to moisture, perspiration and heat sources accelerates ageing. Rubber straps offer greater longevity (8-10 years) but require frequent cleaning to maintain aesthetic appeal.
