Frequently asked questions

What is the lug width of the Tudor Black Bay 79230R-0010?

The lug width of the Tudor Black Bay 79230R-0010 is exactly 22mm. This measurement represents the inner distance between the case lugs' attachment pins. You can verify a strap's compatibility by measuring this distance with a digital calliper: the strap must have a thickness between 3.8 and 4.2mm for a secure fit without play.

What is the best strap for the Tudor Black Bay 79230R-0010?

The best strap depends on intended use. For professional diving, structured rubber or textile NATO straps are recommended as they maintain grip when wet. For formal wear, vegetable-tanned leather in burnt brown or alligator in mahogany brown create an elegant contrast with the black dial. Shell cordovan is ideal for those prioritising durability and resistance to creasing over time.

How do you change the strap on a Tudor Black Bay 79230R-0010?

Position the watch in a dedicated holder or wrapped in soft cloth. Use a spring bar tool to compress the metal pin holding the strap in the case lugs. Push the pin downward gently and simultaneously extract the old strap from the lugs. Repeat on the other lug. To fit the new 22mm strap, align the lugs with the case attachments and press the pin until it clicks, visually verifying it is fully seated.

Are aftermarket straps compatible with the Tudor Black Bay 79230R-0010?

Yes, any 22mm strap of comparable build quality is compatible. Milano Straps offers artisanal 22mm straps constructed with precise thicknesses (3.8-4.2mm) and pre-formed lugs, guaranteeing zero-play fit. Always verify the lug width and strap thickness before purchase to prevent seating issues.

How long does a leather strap last on the Tudor Black Bay 79230R-0010?

Lifespan depends on material and use. A vegetable-tanned Tuscan leather strap typically lasts 2-4 years of daily wear, developing natural patina that distinguishes it. Alligator and shell cordovan offer extended durability of 4-6 years due to denser cellular structure. Moisture exposure accelerates ageing: a watch used in marine environments has a shorter lifespan than one used exclusively in urban settings. Milano Straps provides an 18-month warranty on artisanal straps.
