Strap for Black Bay Blue / Bracelet

The Tudor Black Bay 79220B-0001 features a 22mm lug width. This measurement represents the distance between the two spring bar holes on the watch case. Verification of this specification is essential before purchasing an aftermarket strap, as an incorrect size would result in instability or fitting impossibility.

The selection depends on intended use. For formal and daily-wear contexts, a genuine alligator or Italian vegetable-tanned leather strap in dark tones (moro, cognac brown) enhances the versatile character of the 79220B. For sports and diving use, a durable NATO textile or vulcanised rubber offers superior durability and grip in wet environments. All these materials are available in 22mm sizing compatible with this model's lugs.

Strap replacement requires specific tools: a spring bar tool (lug lever) and a small mallet. Position the lever beneath the lug, compress the internal spring mechanism slightly, and extract the strap. Installation of the new strap follows the reverse process: the spring bar ends are inserted into the lug holes, the strap is positioned, and the spring is released. This operation demands care to avoid scratching the case finish, and professional assistance from a specialised atelier such as Casati Milano is recommended.

Yes, the 79220B-0001 is fully compatible with 22mm aftermarket straps. Milano Straps offers an extensive selection of artisanal straps in various finishes and materials (leather, NATO, rubber, alligator) specifically designed for this lug width. Compatibility is complete, and straps can be personalised in length, initials, and stitching thread colour according to personal preference.

A high-quality leather strap, such as Italian vegetable-tanned leather utilised by Milano Straps, demonstrates a lifespan of 18–36 months with moderate daily wear. Longevity depends on exposure to moisture, perspiration, and the tanning method employed. Vegetable tanning develops a natural patina over time, increasing aesthetic appeal but reducing resistance to weather compared to synthetic methods. Rubber and NATO straps typically last longer (3–5 years) under intensive use. Casati Milano provides an 18-month warranty on all bespoke straps, covering manufacturing defects and stitching failures.
