Strap for Tudor Black Bay 58 79010SG

The lug width of the Tudor Black Bay 58 79010SG is 20mm. This thickness is specific to the 39mm case and represents a balance between historical proportions and modern standards. To verify the measurement correctly, position a digital caliper perpendicular to the two lug pins.

There is no single «best» strap in absolute terms: it depends on intended use and desired aesthetics. Vegetable-tanned alligator in dark brown amplifies vintage character; black calf leather offers formal elegance; navy blue NATO recalls historical military tool watches; grey rubber maintains pure diving functionality. We recommend choosing based on your primary use context.

To change the strap, remove the lug pins: position the watch on a soft pad, use a spring bar tool to compress the pins slightly and slide them through the lug grooves. With the new 20mm strap, align the holes and reinsert the pins until the click fixture engages. If inexperienced, it is advisable to consult a watchmaker or specialised atelier.

Yes, all artisanal straps with 20mm lug width are compatible with the Black Bay 58 79010SG. It is essential to verify that the width is actually 20mm and that the pin thickness matches (usually 1.8mm in standard straps). Bespoke straps allow you to choose material, colour, stitching and finishes, completely adapting the watch to your aesthetic.

The lifespan of a leather strap varies depending on material and use: alligator or shell cordovan in vegetable tanning, with proper maintenance, can last 5-8 years. Quality calf leather typically lasts 3-5 years. Factors such as perspiration, sunlight exposure and ambient humidity accelerate ageing. An FKM rubber strap resists 5-10 years without significant aesthetic deterioration.
