Frequently asked questions

What is the lug width of the Speake-Marin J-Class PIC.10023?

The lug width of the Speake-Marin J-Class PIC.10023 is 22mm, measured from the centre of one lug to the centre of the opposite lug. This measurement ensures compatibility with a vast array of artisan straps without compromising build quality or versatility.

Which strap is most suitable for the Speake-Marin J-Class in red gold?

For the PIC.10023 in red gold, we recommend straps in vegetable-tanned leather with a structured finish, alligator in cognac or honey tones, or waxed calf leather. These materials dialogue naturally with the patina that develops on red gold over time, maintaining the watch's refined character. For a sportier aesthetic, high-density perlon or structured rubber are excellent alternatives.

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

To change the strap, use a spring bar tool—a small, flat instrument specifically designed for this purpose. Insert the tip into the space between the pin and the lug, gently lift the pin upwards to release it, then slide out the old strap and insert the new one. The operation requires patience and precision to avoid scratching the case.

Can you use aftermarket straps on a Speake-Marin J-Class?

Absolutely. The Speake-Marin J-Class PIC.10023, thanks to its standard 22mm lug width, is fully compatible with any artisan 22mm strap. Aftermarket straps in natural Tuscan leather, alligator, or technical materials enable complete personalisation whilst maintaining elevated manufacturing standards.

How long does a leather strap last on this model?

The lifespan of a leather strap depends on daily wear and the quality of the vegetable tanning process employed. A strap manufactured using authentic Florentine vegetable tanning typically lasts between 3 and 5 years with regular wear. Leather develops patina naturally over time, becoming aesthetically more interesting. Factors such as sun exposure, humidity, and sports-oriented use may accelerate wear: rotating between multiple straps periodically extends the life of each one.
