Frequently asked questions

What is the lug width of the Tudor Black Bay Pro M79470?

The Tudor Black Bay Pro M79470 has a lug width of 22 millimetres. This measurement is taken between the lugs (the metal pins on the case where the strap attaches). The 22mm width ensures compatibility with a wide range of aftermarket leather and fabric straps, offering considerable versatility.

What is the best strap for the Tudor Black Bay Pro M79470?

The choice depends on intended use. For formal elegance, an alligator strap in black or dark brown with a stainless steel deployante exudes authority. For tactical robustness, a NATO strap in ballistic nylon or a textured rubber offer superior grip and durability in extreme conditions. A vegetable-tanned calf strap represents the ideal aesthetic compromise: it develops patina over time and maintains visual coherence with the M79470's tool watch profile.

How do you change the strap on the Tudor Black Bay Pro M79470?

The strap is changed using a spring bar tool. Insert the thin tip of the tool under the lug, press to compress the internal spring, and extract the pin from the case. Once removed, insert the new strap into the case holes and reinsert the pin from the opposite side. This is a straightforward, reversible operation when performed with precision.

Is an aftermarket 22mm strap compatible with the Tudor Black Bay Pro M79470?

Yes, any strap with a 22mm lug width is compatible with the M79470, provided it has suitable pins or is easily adaptable. Artisanal straps from Milanostraps are specifically manufactured in this width and tested on watches in this category. Compatibility is guaranteed in both width and depth.

How long does a leather strap last on a watch like the Tudor Black Bay Pro M79470?

Leather strap longevity varies based on material, tanning method, and usage. Premium alligator can last 5-7 years with regular maintenance (cleaning with a damp cloth, rapid drying after water exposure). Vegetable-tanned calf, being softer, has an average lifespan of 3-5 years, with the advantage of visible patina development. Rubber straps typically last 2-3 years before showing signs of hardening.
