Strap for Heritage Black Bay Blue Manufacture / Bracelet

The lug width of the Tudor Black Bay 79230B-0008 is 22mm. This standard represents the ideal lug measurement for the 41mm case diameter, ensuring harmonious proportions and correct elastic tension on the lugs. To verify the measurement on your watch, measure the distance between the two inner lugs using a digital calliper.

The ideal strap depends on your intended use. For daily luxury wear, we recommend alligator with vegetable tanning, which develops a natural patina over time. For sport and diving use, a premium NATO strap in regenerated yarn maintains the model's military heritage. Brushed calfskin offers versatility for daily alternation, whilst FKM rubber remains the technical solution for frequent water exposure.

Strap replacement is performed via a spring bar positioned vertically in the case lugs. Remove the old strap by gently pushing the spring bar downward to free the end from the lug, then insert the new strap whilst keeping the spring bar tense. The operation requires minimal tooling (spring bar tool or fine tweezers) and 30 seconds per lug. If preferred, Casati Milano provides professional installation service.

Factors influencing longevity include: frequency of humid climate changes, prolonged direct sunlight exposure, acidic perspiration. Vegetable tanning allows renewal through patina restoration.
