Strap for Heritage Black Bay Bronze One Only Watch 2017

The Tudor Black Bay Bronze 7925/001 features a lug width of 23mm, measured internally from one lug shoulder to the other. This dimension is specific to the model and determines compatibility with any aftermarket strap. To verify correctly, position a digital calliper perpendicular to the lugs of the case.

We recommend alligator leather in dark brown or shell cordovan in burgundy, both with vegetable tanning. These materials develop patina over time parallel to the bronze case, creating coherent aesthetic evolution. For authentic diving use, FKM rubber in black represents the purposeful option.

Use a spring bar tool to compress the springs beneath each lug. Once both springs are extracted, the strap will release from the case. To install a new 23mm strap, insert the pin into the first lug with one spring already positioned, then press the second spring into the upper hole until it clicks into place. Repeat for the other lug.

Yes, provided it is manufactured to correct tolerances. Quality aftermarket straps from reputable brands are compatible. However, verify thickness: the strap should measure between 4 and 5.5mm for secure fit without tension on the case. Milano Straps 23mm options are certified for this model.

A quality leather strap with vegetable tanning maintains structural functionality for 3-5 years under moderate use. If subjected to regular diving and marine environments, durability reduces to 18-24 months for untreated leathers. A rubber FKM or cotton NATO strap offers greater longevity in extreme diving contexts.
