The Black Bay One 79600-0001 (aka: M79600-0001), seen from the bench

The Tudor Black Bay One 79600-0001 is a 31mm stainless steel watch that revisits the compact proportions of the 1950s Submariner 6536. The satin-finished case features a unidirectional black ceramic bezel and screw-down crown. It is powered by the Tudor caliber MT5201 movement with manual winding, 28,800 vibrations per hour, and approximately 70 hours of power reserve. The white dial with applied indices and Mercedes hands, sapphire crystal with anti-reflective coating on the caseback, and 17mm lug width complete this design that prioritizes legibility and functional construction over decorative elements.

Frequently asked questions

What is the exact lug width of the Tudor Black Bay One 79600-0001?

The Tudor Black Bay One 79600-0001 features a lug width of 17 millimetres. This dimension is specific to this model and results from the balanced proportion between the compact 31mm diameter and the case width. To verify strap compatibility, always measure the internal distance between the lugs, or consult the manual supplied with your watch.

Which strap material do you recommend for the Black Bay One 79600-0001?

For the Black Bay One 79600-0001, genuine alligator leather with vegetable tanning is the optimal choice: it develops a natural patina over time that amplifies the tactile narrative of the satin case, provides natural grip through scale structure, and absorbs pressure, reducing stress on the stem and lugs. Alternatively, shell cordovan ages beautifully with natural lustre, whilst English calf with vegetable tanning offers a balance between resilience and understated elegance.

How do I change the strap on a Tudor Black Bay One 79600-0001?

To change the strap on your Tudor Black Bay One 79600-0001, use a dedicated spring bar removal tool. Position the watch with the strap facing you, insert the tool into the lateral hole of the pin and gently push to free the pin from the first lug. Repeat for the second lug. Proceed with care to avoid scratching the satin case. If inexperienced, entrust the task to a specialist atelier such as Casati Milano.

Can I use an aftermarket strap compatible with 17mm lug width?

Yes, any strap with 17mm lug width is mechanically compatible with the Tudor Black Bay One 79600-0001. However, we recommend selecting materials and finishes that respect the aesthetic integrity of the watch: alligator, vegetable-tanned calf, reinforced canvas. High-quality artisanal aftermarket straps, such as those available on milanostraps.it, maintain elevated standards of constructive precision and controlled ageing.

What is the average durability of a leather strap for the Black Bay One?

A high-quality leather strap with vegetable tanning (alligator, calf, cordovan) typically lasts 3-5 years with moderate daily wear, provided it receives periodic maintenance. Prolonged sweat exposure accelerates wear; intense cold and high humidity require regular ventilation. Canvas or rubber straps offer superior durability (5-7 years), especially when worn alternately. Milano Straps' artisanal straps, crafted from premium leathers and meticulous stitching, guarantee certified resistance within 18 months of personalised creation.
