Frequently asked questions
What is the lug width of the Tudor Black Bay One 79680-0003?
The Tudor Black Bay One 79680-0003 features a lug width of 22 millimetres. This measurement, also called strap width or ansa in Italian tradition, indicates the internal distance between the two lugs on the case where the strap is attached. You must select straps specifically cut for 22mm to ensure proper fit with your timepiece.
What is the best strap for the Tudor Black Bay One 79680-0003?
The optimal choice depends on intended use and aesthetic preferences. To complement the night blue dial and brushed steel case, we recommend a dark brown alligator with aged patina, or vegetable-tanned leather that develops character over time. For formal occasions, burgundy shell cordovan elevates sophistication. A grey anthracite NATO fabric maintains daily versatility, whilst a black rubber strap returns the piece to its professional diving heritage with understated refinement.
How do I change the strap on the Tudor Black Bay One 79680-0003?
Strap replacement requires a specialised tool—either strap removers or a spring bar punch—and careful attention to construction details. Locate the spring bars securing the strap to the case lugs. Using the remover, gently push the bar outward until it fully disengages. Remove the old strap, align the new one with the case shoulders, and reinsert the spring bar with gentle pressure until it seats firmly. If you prefer professional handling, Casati Milano offers personalised mounting with warranty coverage.
Which aftermarket strap is compatible with the Tudor Black Bay One 79680-0003?
Any strap with a 22 millimetre lug width is mechanically compatible. Milano Straps provides a complete collection of artisanal 22mm straps—from alligator to calf leather, shell cordovan to NATO fabric—all customisable in colour, initials and stitching type. Always verify that strap thickness respects the visual proportions of the case and that attachment points match your specific reference.
How long does a leather strap last on the Tudor Black Bay One 79680-0003?
Leather strap longevity depends on construction quality, stitching technique and environmental exposure. A well-crafted alligator or vegetable-tanned calf strap typically lasts 5–8 years under daily wear. Vegetable-tanned leather develops aesthetic patina and unique colour shifts naturally. Leather requires protection from extreme moisture and periodic cleaning with a soft cloth. Milano Straps pieces include an 18-month guarantee and may be restored by our atelier to extend functional lifespan.
