Frequently asked questions

What is the lug width of the Tudor Black Bay One 79613?

The Tudor Black Bay One 79613 features a 16mm lug width. This measurement is specific to this compact model and must be respected when selecting an aftermarket strap. Correct measurement is performed using a digital calliper, measuring from the inner left edge of the lug to the inner right edge, with a construction tolerance of ±0.5mm.

Which strap is most suitable for the Tudor Black Bay One 79613?

A high-quality alligator strap or vegetable-tanned calf leather represents the most aesthetically coherent choice for the 79613. For sports applications, an FKM rubber deployante offers resistance to salt water. The fine grain and natural patina amplify the tool watch character without decorative excess.

How do you change the strap on a Tudor Black Bay One 79613?

Position the watch on a stable support. Use a spring bar remover or thin blade to apply perpendicular pressure to the lug pin, pushing it outward. Once the pin is extracted, the strap separates from the case. Insert the new strap by aligning the lugs with the pins and reinsert the pin until it clicks. Verify perfect alignment before wearing.

Is an aftermarket strap for the Tudor Black Bay One 79613 compatible with other models?

A 16mm strap made for the 79613 is not compatible with other Tudor models featuring different lug widths (20mm for standard Black Bay, 22mm for larger models). The 16mm specification is exclusive to compact models such as the 79613. Always verify your watch's lug width before purchase.

How long does a leather strap last on the Tudor Black Bay One 79613?

Durability depends on material and usage. An alligator strap with vegetable tanning, worn daily in non-aquatic environments, typically lasts 3-5 years before replacement. FKM rubber has superior durability (5-7 years) due to mechanical resistance. Regular maintenance (gentle cleaning, drying, conditioning every 6-8 months) significantly extends service life.
