Strap for Tudor Black Bay 79250BB

The lug width of the Tudor Black Bay 79250BB is 23 mm. This width is measured internally between the case lugs and represents an intermediate standard requiring careful selection among aftermarket solutions. An incorrectly sized strap will not fit properly into the suspension pins.

The best strap depends on intended use and aesthetic preference. Vegetable-tanned alligator in brown or dark bottle-green offers sartorial elegance, vegetable-tanned calf with flame finish in dark tones follows the natural ageing of bronze, whilst FKM rubber straps provide practicality and water resistance for sports use. Textile NATO straps add a vintage maritime element.

The strap is changed by removing the spring bars using a dedicated tool. The pins are gently extracted from the case lugs, the old strap removed and the new one inserted. It is essential to verify that the 23 mm strap has a thickness of 4–5 mm to ensure stable seating without lateral play.

Yes, any strap with 23 mm lug width is dimensionally compatible. However, construction quality, thickness, edge finishing and type of tanning significantly influence the aesthetic result and durability. An artisanal strap guarantees precision in lug cutting and material selection consistent with the Black Bay standard.

A natural leather strap lasts between 3 and 5 years, depending on use, tanning method and climatic conditions. Vegetable tanning, more durable but subject to visible ageing, favours natural patina. Exposure to humidity, intense sunlight and mechanical wear accelerate deterioration. Proper maintenance and rotation between multiple straps extends lifespan.
