Strap for Style 34 Stainless Steel / Blue / Strap

The lug width of the Tudor Style 12300-0016 is 20mm. This measurement represents the distance between the two case lugs and determines compatibility with aftermarket straps. A 20mm strap slides into the lugs without play, ensuring stability and precise fit. To verify this measurement, place a ruler between the inner points of the lugs from one side to the other: you will find exactly 20mm.

The Tudor Style 12300-0016 pairs naturally with alligator or calf leather straps, especially those treated with vegetable tanning. Black or chocolate brown alligator emphasises the formal character of the 34mm case, whilst grey-brown or burgundy calf creates a temporal connection with natural patina development. For more casual occasions, technical fabric or NATO straps offer contemporary versatility without stylistic compromise. Your choice depends on the dial of your model: blue dials pair well with chocolate brown or grey-brown; black dials with black alligator or burgundy calf.

To change the strap on your Tudor Style 12300-0016, you will need a specific tool: a spring bar tool or small flathead screwdriver. Position the watch with the strap facing upwards, locate the small hole on the side of the lug, insert the spring bar tool into the hole to release the internal spring and gently slide the old strap outward. Insert the new 20mm strap into one of the lugs and, using the same tool, align the spring into the hole of the other lug. Practice and care prevent scratches on the case.

Absolutely. Any strap with a 20mm lug width is compatible with the Tudor Style 12300-0016, provided it respects the same measurements and appropriate thickness. The artisanal straps from milanostraps.it, available in alligator, calf, shell cordovan and fabric, are specifically cut for this lug width. A quality aftermarket strap often improves the wearing experience compared to the original, allowing customisation in colour, material and perforation count suited to your wrist.

The lifespan of a leather strap depends on maintenance, climate and frequency of use. A well-maintained vegetable-tanned calf lasts an average of 3-5 years, developing a desirable patina that increases aesthetic value. An alligator, if protected from excess moisture and heat, can exceed 5 years. The artisanal straps from Casati Milano are guaranteed for 18 months and made from premium selected leathers. To extend useful life, avoid prolonged exposure to water, sweat and direct sunlight. Occasional cleaning with a soft, dry cloth maintains leather condition. Periodic replacement is a natural part of owning a quality watch.
