Strap for Tudor Black Bay Chronograph M79360B

The Tudor Black Bay Chronograph M79360B features a 22mm lug width, which is the distance between the two pins connecting the strap to the case. This measurement is compatible with the extensive range of artisanal straps available in this standard size. To verify the lug width with accuracy, use a digital calliper and measure the internal distance between the two attachment pins at the top lug.

The optimal strap choice depends on intended usage and aesthetic preferences. For formal occasions, we recommend a crocodile or alligator strap in black or dark brown with fine grain, which harmonises with the brushed steel case. For daily wear, Italian calf leather with vegetable tanning offers softness and develops natural patina over time. For sports or water activities, an FKM rubber strap provides water resistance and practicality. Shell cordovan is ideal for those appreciating the visible evolution of leather patina.

Position the watch with the case facing upward and identify the two pins passing through the lugs. Using a spring bar removal tool (a small implement with a slot), gently depress the spring mechanism of one pin: you will notice tension from the internal spring. Remove the pin carefully and extract the old strap. Repeat on the opposite side. Insert the pins of the new strap and verify that the spring mechanisms click securely into position. The operation requires approximately 2-3 minutes and is easily performed at home without specialised equipment.

Yes, the M79360B utilises standard 22mm pins and is fully compatible with any quality aftermarket or artisanal strap measuring 22mm. Straps manufactured by specialised ateliers such as Casati Milano guarantee flawless finishing, controlled leather selection and ergonomic wrist adaptation. There are no constructive limitations preventing the use of non-original straps, provided they respect the 22mm lug width specification.

Lifespan depends on material, tanning method and usage intensity. A crocodile or shell cordovan strap, with regular maintenance (cleaning with a damp cloth, occasional neutral balm application), can remain functional for 5-7 years or longer. Calf leather with vegetable tanning offers comparable durability, developing desirable patina. An FKM rubber strap maintains elasticity and resistance for 3-4 years before showing initial signs of ageing. The artisanal strap from Casati Milano, thanks to its 18-month warranty and premium leather selection, offers exceptional durability extending well beyond the warranty period.
