Strap for Style 34 Stainless Steel / Silver / Bracelet

The lug width of the Tudor Style 12300-0017 is precisely 20mm. This dimension is standard for dress watches of compact diameter and is the critical parameter for selecting compatible straps. It is essential to measure the lug width parallel to the case at the point of maximum width between the two lugs, not on the external case surface.

For a dress watch such as the Style 12300-0017, an alligator strap in vegetable tanning represents the purest choice, with regular texture and evolving patina over time. Alternatively, calf leather in vegetable or chrome tanning offers versatility and aesthetic simplicity. For those seeking practicality, silk or cotton/linen NATO straps emphasise the compact diameter of the case, whilst FKM rubber is ideal for intensive use.

The strap is removed using a spring bar tool: insert the flat tip under the spring end of each lug, gently compress the spring, and pull the strap downward. The process is reversible. When installing the new strap, align the holes with the lugs, compress the springs and verify tightness. If unfamiliar with the procedure, entrust the task to a professional watchmaker.

Yes, any quality 20mm strap is compatible with the lugs of the Tudor Style 12300-0017, provided the leather thickness permits smooth insertion. Verify that the spring bar is intact and that the strap has no grain or finishes that might damage the polished steel case. MilanoStraps supplies straps specifically tested for this model.

A quality leather strap (alligator or calf) typically lasts 5-7 years with moderate daily use. Longevity depends on tanning method, thickness, frequency of use and moisture exposure. Vegetable tanning tends to age more gracefully than chrome tanning, developing an appreciated patina over time. Periodic maintenance with specific conditioners significantly extends longevity. MilanoStraps straps include an 18-month warranty.
