Strap for Style 34 Stainless Steel / Fluted / Silver-Diamond / Bracelet

The Tudor Style 12310-0007 features a lug width of 20 millimetres. This measurement indicates the horizontal distance between the two lugs of the case where the strap attaches. This technical specification is essential when purchasing aftermarket straps, as an incorrect lug width will result in poor installation with unsightly protrusions on the sides of the case.

For the 34-millimetre Tudor Style 12310-0007, genuine alligator straps (natural grain, cognac brown), hand-finished calf leather (fine texture, formal tones), or cotton-linen NATO straps (sporty practicality) are recommended. Your choice depends on occasion: uniform leathers for formal settings, NATO for everyday wear. A vegetable-tanned leather strap represents the most conscious choice, as it develops a natural patina over time.

Strap replacement requires simple tools: a spring bar tool to remove the lugs from the original strap, or a small flathead screwdriver. Position the watch on a soft surface (cloth, mat) to avoid scratches. Insert the tool into the lateral lugs, gently remove the spring bar under tension, and extract the strap. Reverse the installation for the new strap, ensuring the springs position symmetrically on both sides.

Yes, provided the lug width is 20 millimetres. All straps of this width are compatible with the 12310-0007, regardless of material (leather, rubber, textile). On milanostraps.it you will find an extensive selection of 20mm straps customisable in dimensions, initials and stitching type, ensuring maximum aesthetic and functional compatibility.

The durability of a leather strap varies depending on material and usage. A genuine alligator or fine calf leather strap typically lasts 3–5 years with daily wear. Vegetable-tanned leather ages better, developing patina whilst maintaining structure for 4–7 years. Exposure to water, humidity and heat accelerates deterioration. High-quality aftermarket straps, such as those offered by milanostraps.it, are crafted from selected leathers that maintain superior performance, with an 18-month warranty available through Casati Milano.
