Strap for Magister Tourbillon

The lug width of the Speake-Marin J-Class PIC.10031 is 22mm. This measurement represents the internal space between the two lugs of the case where the strap attaches. It is essential to respect this dimension to ensure proper insertion and absence of lateral play.

For the PIC.10031 in rose gold, straps in American alligator with vegetable tanning (for ageing patina) or burgundy shell cordovan (for chromatic synergy) are recommended. French calfskin with vegetable tanning offers a soft and versatile alternative. For casual wear, NATO straps in neutral tones ensure quick changes and superior comfort.

Strap replacement requires removal of the spring bar (passant pin) that connects the strap to the lug. Using a dedicated tool (spring bar removal tool or ball removal tool), push the elastic pin inward to disengage it from one side, then remove the strap. Insert the new strap by aligning it with the lugs and push the pin until it clicks. For valuable timepieces, specialist assistance is recommended.

Yes, any strap in 22mm lug width is compatible with the PIC.10031. It is essential to verify that it is exactly 22mm (not 20 or 24mm). Artisanal leather straps, NATO fabric and FKM rubber are all compatible. We recommend specialised brands in 22mm lug width to guarantee construction precision and reliable craftsmanship.

A high-quality vegetable-tanned leather strap (alligator, shell cordovan, French calfskin) lasts 3-5 years with moderate daily wear. Durability depends on factors such as frequency of wear, sun exposure, humidity and maintenance (periodic leather conditioning). A NATO strap or FKM rubber offers superior durability (5-10 years) with less need for maintenance.
