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

The lug width of the Tudor Style 12313-0009 is 20mm, a dimension that qualifies this dress watch as proportionally designed for slender to medium wrists. Measurement should be conducted with a digital calliper between the two horizontal lugs of the case, not from the total strap width. This dimension is standard in the contemporary and vintage women's watch segment, allowing a broad selection of specialised straps.

Alligator in neutral tones (black, dark brown, pearl grey) is the most noble choice for this timepiece, creating a sophisticated dialogue with the bi-colour case. European calfskin in vegetable tanning offers natural patina development and constructive authenticity. Well-executed shell cordovan provides containment in rigidity and subtle lustre. NATO in cotton-nylon is ideal for informal environments, protecting the movement from moisture. Selection must balance case aesthetics, daily comfort and patina development over time.

Changing the strap on the 12313-0009 requires a tool called a spring bar remover. Position the tool in the small lateral hole of the lug and apply gentle pressure to compress the internal spring, allowing the lug to slide out of the bar. Manual forcing is not recommended to avoid case damage. A specialised atelier such as Casati Milano offers free strap changing service for straps purchased from our 20mm catalogue.

Yes, a standard 20mm strap is fully compatible with the 12313-0009, provided the width is measured correctly between the lugs. However, it is necessary to verify that the strap thickness does not exceed 3.5-4mm on the underside (the side in contact with the wrist), otherwise the strap will appear visually disproportionate to the 34mm case. High-quality straps from artisanal ateliers, such as those from Casati Milano, are constructed with proportions calibrated for women's dress watches.

A natural leather strap subjected to daily use on a dress watch such as the 12313-0009 has an average lifespan of 3-5 years, dependent on the type of tanning, solar exposure, moisture and frequency of use. Vegetable tanning, being poorer in synthetic oils, tends to age more nobly but requires periodic maintenance (conditioning with natural waxes). An alligator or shell cordovan strap, if properly stored, can exceed 7-10 years. The standard warranty on artisanal straps is 18 months, with the possibility of renewal through restoration at the atelier.
