⭕️ Instant purchase ❌ Price reduction This is a genuine Tudor rubber strap. The lug width is 20mm, compatible with Black Bay 54 (M79000). Size has been adjusted (described below). I used it for one month (3-4 times a week). There are some scratches on the stainless steel part of the buckle, but it is generally in good condition. ◇ About the size All the links have been removed, and it is at its shortest length. With the T-fit at its shortest setting, it fits my wrist (actual size about 15.5cm) perfectly. The T-fit on the rubber strap can be adjusted by a maximum of +12mm, so it should fit comfortably for those with a wrist size of 15-16cm. It may be possible to wear it with a 16.5cm wrist, but there might be less room. However, the adjustment depends on personal preference, so please use this as a reference only.
