Datejust 31 178158-0067— lug 16mm

The Rolex Datejust 31 ref. 178158-0067 has a lug width of 16mm. This measurement should be verified using a digital calliper, measuring the internal distance between the two lugs at the strap attachment point. Respecting this specification is essential to ensure a secure and rattle-free fit.

For an 18-carat yellow gold case, alligator straps in belly or hornback grain in cognac, burgundy or tobacco brown tones provide the most harmonious aesthetic pairing. Shell cordovan and vegetable-tanned calf leather are excellent alternatives, offering durability and a developing patina over time. A yellow gold buckle or deployant clasp ensures metallic consistency throughout.

The strap on a Rolex Datejust 31 is removed using a spring bar tool to release the spring bars connecting the strap to the case lugs. Care must be taken to avoid scratching the yellow gold lugs: a tool with a plastic or nylon tip is strongly recommended. If in doubt, the operation should be entrusted to a qualified watchmaker.

Yes. Aftermarket 16mm straps with shaped ends designed for Rolex lugs are available in leather, rubber and nylon. Milano Straps produces handcrafted straps specifically compatible with this model, supplied with stainless steel spring bars and buckles or deployant clasps in various metals, including yellow PVD to match the gold case.

The lifespan of a leather strap depends on the material and frequency of use. A quality alligator strap worn regularly but not during sports activities typically lasts between two and five years before requiring replacement. Shell cordovan and vegetable-tanned calf leather tend to outlast standard leathers due to their denser fibre structure. Exposure to perspiration, water and perfume accelerates wear; rotating between multiple straps significantly extends the life of each one.
