Strap for La Chaux-de-Fonds Petite Seconde Rétrograde Tourbillon Stainless Steel / Green Aventurine

The lug width of the WCF22TSE06SS01AA model is precisely 22mm. This measurement represents the distance between the two case lugs and is crucial for ensuring correct installation of any aftermarket strap. Verifying this dimension with a calliper before purchase is essential to avoid incompatibilities.

For a timepiece of such technical complexity and value, we recommend a strap in natural alligator leather or vegetable-tanned calf leather. Alligator, with its characteristic texture of parallel scales, harmonises beautifully with the architectural geometry of the stainless steel case. Vegetable-tanned calf develops a compelling patina over time. Both maintain the aesthetic dignity of the timepiece and the ceremonial character of the tourbillon movement.

Strap replacement follows the standard procedure: position the watch on a soft pad, then use a spring bar tool (small metal device) to apply pressure to the sprung lugs. Push gently on one side to release the end of the pin, extract it, then repeat on the other side. The operation requires patience and precision, especially given the value of the case. It is advisable to have the change carried out by a specialised retailer.

All straps with a 22mm lug width are compatible with the Schwarz Etienne WCF22TSE06SS01AA. This includes straps in alligator, calf, shell cordovan, natural and synthetic rubber, as well as NATO and fabric straps. The important thing is to verify that the width is exactly 22mm and that the length of the strap is appropriate for your wrist. MilanoStraps offers a complete selection of 22mm straps crafted by hand.

The durability of a leather strap depends on the quality of the material and the intensity of use. A high-quality artisanal alligator or vegetable-tanned calf strap can last 5-8 years with careful daily wear. The leather develops a patina that testifies to the time worn. Factors such as humidity, prolonged sun exposure and perspiration accelerate ageing. Proper maintenance – drying the strap if wet, avoiding extreme bends – will significantly extend its useful life.
