Frequently asked questions

What is the lug width of the Speake-Marin J-Class PIC.10005-02?

The lug width of the Speake-Marin J-Class PIC.10005-02 is 22 mm. This measurement represents the internal distance between the two lugs on the case and is essential for selecting a compatible strap. To verify, use a digital calliper inserted perpendicularly into the lug shoulders: the result must be exactly 22 mm.

Which strap is recommended for the Speake-Marin J-Class in rose gold?

For the PIC.10005-02 in rose gold, we recommend three primary options: an alligator strap in dark cognac colour, which enhances the warmth of the gold and creates chromatic continuity; a shell cordovan in natural burgundy, which develops an extraordinary patina over time; a vegetable-tanned calf leather in tobacco shade, ideal for daily wear. A rose gold deployant clasp completes the ensemble with material coherence.

How do you change the strap on a watch with 22 mm lug width?

Strap replacement requires a specific tool: the spring bar tool. Position the watch on a soft surface (cloth, silicone mat). Insert the flat end of the spring bar tool at the end of the lug, gently pushing to compress the internal spring. Once released, remove the old strap and replace it with the new 22 mm strap, ensuring the lugs insert smoothly without excessive play.

Is the Speake-Marin J-Class PIC.10005-02 compatible with quality aftermarket straps?

Absolutely. The J-Class with 22 mm lugs is entirely compatible with high-quality aftermarket artisanal straps. Given the balanced case proportions (42 mm), the lug width allows pairing with structured straps in fine leather (alligator, shell cordovan, calf) as well as textile (NATO) or watchmaking rubber. Ensure the new strap is measured precisely at 22 mm.

What is the average lifespan of a leather strap on the Speake-Marin J-Class?

A fine leather strap (alligator or shell cordovan) of superior quality, worn daily on the Speake-Marin J-Class PIC.10005-02, maintains structure and functionality for 3-5 years. Longevity depends on ambient humidity, sun exposure, and frequency of use. Vegetable-tanned calf tends to develop patina more rapidly but remains reliable for at least 4-6 years. Rotating between multiple straps significantly extends the useful life of each.
