Strap for Black Bay 36 S&G - Diamond / Anthracite - Diamond / Bracelet

The Tudor Black Bay One, reference 79653-0003, features a 19-millimetre lug width. This measurement represents a distinctive design choice and constitutes a relatively uncommon dimension in contemporary horology, necessitating careful selection when purchasing an aftermarket strap.

For a two-tone case in yellow gold and stainless steel, an alligator strap in cognac tone offers supreme aesthetic coherence: the characteristic grain of the leather dialogues naturally with the warmth of gold, and the patina that develops over time amplifies this harmony. Alternatively, vegetable-tanned calf in havana represents a more conscientious choice from a sustainability perspective, whilst maintaining refined visual contrast.

To change the strap, employ a spring bar removal tool. Position the tool in the slot of the spring bar retention mechanism, lift gently to liberate the bar from the lug hole, then extract the old strap. Align the new strap's holes with the lug ends, reinsert the spring bar, and verify secure seating on both sides.

Absolutely. The sole technical constraint is the 19-millimetre lug width: any leather, rubber, or fabric strap with an internal width of 19 millimetres is compatible. It is advisable to favour models featuring a deployant clasp to minimise mechanical stress upon the lugs during daily wear.

A fine leather strap—alligator, calf, or shell cordovan—maintains full functionality for 5 to 7 years of daily use, provided elementary maintenance: avoid prolonged water immersion, protect from excessive heat, and periodically apply a specialist conditioning agent for watch leathers. Patina and aesthetic aging constitute part of the authentic experience of an artisanal strap of quality.
