The 22mm lug width is optimally proportioned for the 39mm case and ensures secure strap attachment.

Frequently asked questions

What is the lug width of the Tudor Black Bay Pro 79470-0002?

The lug width of the Tudor Black Bay Pro 79470-0002 is 22mm. This measurement is standard for this family and requires specifically-sized 22mm watch straps. To measure correctly, calculate the distance between the internal holes of the integrated lugs on the case, not the visible external diameter. An inaccurate measurement may result in straps that are either too wide or too narrow.

Which strap do you recommend for the Tudor Black Bay Pro?

For the Black Bay Pro 79470-0002, we recommend leather in vegetable tanning (alligator or calf) in Testa di Moro brown or cognac tones for multi-purpose applications, or shell cordovan for an evolved patina over time. For marine or tactical use, FKM rubber in grey-black ensures zero saltwater absorption and minimal maintenance. NATO in cotton is the versatile alternative for dedicated outdoor contexts. Avoid synthetic or stamped leather straps: the tool watch profile of the Black Bay Pro demands materials that age nobly.

How do I change the strap on my Tudor Black Bay Pro 79470-0002?

The Tudor Black Bay Pro features integrated lugs with MM threading. The procedure requires: 1) position the watch on a soft pad; 2) use a spring bar tool or small flat screwdriver; 3) insert the tool into the lateral access hole of the lug; 4) gently lever to eject the spring bar; 5) remove the old strap; 6) insert the new strap and verify the lock. Do not apply excessive force: MM threading is precise and requires no violent pressure.

Which aftermarket straps are compatible with the Black Bay Pro 79470-0002?

All artisanal straps with 22mm lug width are compatible with the Tudor Black Bay Pro 79470-0002, provided the spring bars are correctly dimensioned for the integrated MM-threaded lugs on the case. On milanostraps.it you will find personalizable straps in natural leather, vegetable tanning and technical rubber, all adjustable in length for your wrist. Always verify that the retailer specifies compatibility with 22mm cases before purchase.

How long does a leather strap last on the Black Bay Pro?

A high-quality leather strap (vegetable tanning, alligator or shell cordovan) on a tool watch such as the Black Bay Pro 79470-0002 lasts 3-5 years with regular daily use before replacement is necessary. Vegetable-tanned leather ages nobly: it develops patina, colours shift towards darker tones, fibres consolidate. With occasional maintenance (light cleaning, natural balm application), the strap can extend its life to 6-7 years. FKM rubber lasts longer (7-10 years) with no aesthetic changes. Critical factors include: relative humidity in your environment, frequency of use, and exposure to prolonged direct UV radiation.

How can I personalise a 22mm strap at Casati Milano?

The procedure involves: telephone or WhatsApp consultation to indicate your Tudor model and aesthetic preferences; personal selection among available leathers (alligator, cordovan, calf in vegetable tanning); definition of specific length (measured from previous strap or direct measurement); selection of stitching thread colour and any engraved initials. All bespoke straps benefit from an 18-month guarantee on craftsmanship.
