Frequently asked questions

What is the lug width of the Speake-Marin J-Class PSM OW2015?

The lug width of the Speake-Marin J-Class PSM OW2015 is 22 millimetres. This measurement represents the distance between the two vertical lugs where the watch strap is attached. It is a specific dimension requiring bespoke compatible straps rather than standard off-the-shelf options.

Which strap do you recommend for this red gold model?

For a red gold PSM OW2015, we recommend alligator leather in dark brown or burgundy tones, or alternatively a vegetable-tanned calf in cognac. Both enhance the warmth of the noble metal. NATO fabric straps or grey taupe calf offer versatility while maintaining elegance and refinement.

How do I change the strap on the Speake-Marin J-Class?

Remove the spring bars that hold the strap in place on the lugs. Use a spring bar tool to carefully compress the end pin, then extract it gently from the lug. Once removed, the old strap detaches. To install a new strap, align the holes with the lug pins and reinsert the spring bars with the spring mechanism facing inward.

Can I use a third-party aftermarket strap in 22mm?

Yes, absolutely. Bespoke 22mm aftermarket straps are fully compatible with the Speake-Marin J-Class PSM OW2015. It is essential to verify that the lug width is precisely 22mm to avoid excessive play or installation difficulties. Milano Straps manufactures artisanal straps certified for this measurement.

What is the average lifespan of a leather strap for this watch?

A quality leather strap—whether vegetable-tanned or alligator—typically lasts 3–5 years with moderate daily use. Longevity depends on humidity exposure, perspiration, and UV light. A leather strap will naturally age, developing patina over time. To extend lifespan, we recommend periodic cleaning and storage in a dry environment.
