The Black Bay One 79500-0015 (aka: M79500-0015), seen from the bench

The Tudor Black Bay One 79500-0015 celebrates 60 years of the Black Bay family with deliberate simplicity: no rotating bezel, no date window, no dial branding. Powered by the Tudor T600 caliber (4 Hz frequency, 70-hour power reserve, COSC-certified balance), the 36mm stainless steel case offers essential functionality. Case thickness 11.3mm, water resistance 70m, 19mm lug width. A proportional return to 1960s sports watch standards.

Frequently asked questions

What is the lug width of the Tudor Black Bay One 79500-0015?

The Tudor Black Bay One 79500-0015 features a 19mm lug width. This dimension is proportioned to the 36mm case diameter and ensures optimal aesthetic balance. To verify compatibility, measure the internal distance between the two lugs on your watch case: it must be exactly 19mm.

What is the best strap for the Tudor Black Bay One?

Vegetable-tanned alligator represents the most harmonious choice: natural texture contrasts elegantly with the brushed steel case. Shell cordovan offers superior luminosity and durability with genuine ageing patina. For daily urban use, regenerated calf provides practicality and wear resistance. In formal contexts, pair alligator cognac or black with a stainless steel deployante buckle.

How do you change the strap on the Tudor Black Bay One 79500-0015?

Use a dedicated pin remover tool, available from any watchmaker. Position the watch dial-side down, insert the pin remover into the slot of the pin securing the strap, and gently extract the metal pin by pushing it upwards. Repeat on the second lug. Once the pins are removed, slide off the old strap and install the new one by reversing the procedure.

Are there aftermarket straps compatible with the Tudor Black Bay One?

Yes. On milanostraps.it you will find a dedicated collection of 19mm straps specifically compatible with the 79500-0015. All are crafted from premium leathers (alligator, cordovan, calf) and customisable in size, initials, and stitching type. Atelier Casati Milano also offers direct consultation and bespoke strap creation with 18-month warranty.

How long does a natural leather strap last on a sports watch like the Black Bay One?

A high-quality vegetable-tanned leather strap typically lasts 3-5 years with daily wear and proper maintenance. Longevity depends on frequency of use, climatic conditions, and tanning method employed. Vegetable-tanned alligator and cordovan age beautifully, developing aesthetic patina over time. To extend durability, avoid prolonged moisture exposure and occasionally apply a natural leather conditioner.
