What I'm asked about the Wyler Vetta Jumbostar WV0405

What strap size does the Wyler Vetta Jumbostar WV0405 take?

The Wyler Vetta Jumbostar WV0405 needs 20 mm between the lugs, usually 16 mm at the buckle. It's the size I've been fitting on it for years.

Can the strap on the Wyler Vetta Jumbostar WV0405 be changed?

Yes. It has spring bars between the lugs: with the right tool the strap comes off in a minute. If you'd rather not risk a scratch, I do it in the workshop.

Can I put a leather strap on the Wyler Vetta Jumbostar WV0405?

Yes, in 20 mm leather. On a 40 mm case a calf strap works every day; if you want something more, alligator.

Which strap do you recommend for the Wyler Vetta Jumbostar WV0405?

A 20 mm calf strap, for every day. You'll find it ready in the 20 mm collection. If you'd rather have something built on your wrist, the Casati atelier.

The Jumbostar WV0405, seen from the bench

The Wyler Vetta Jumbostar WV0405 is a 1970s sports chronograph with a 40mm stainless steel case and 48mm lug-to-lug. Powered by an ETA 2894 automatic movement with 42-hour power reserve and 28,800 vph, it features functional Scandinavian-Swiss design typical of post-war Swiss watchmaking. The 20mm lug width is precisely measured internally between the lateral pins.

Frequently asked questions

Are compatible aftermarket straps available for the WV0405?

Yes, numerous high-quality aftermarket solutions exist for 20mm lugs. Always verify compatibility: internally 20mm (lug width) and do not confuse with the visible strap width.

How long does a natural leather strap last on a daily-wear watch like the WV0405?

A quality leather strap (calf, alligator, vegetable-tanned shell cordovan) typically lasts 5–8 years with daily use and appropriate maintenance. Longevity depends on humidity exposure, perspiration, UV rays, and cleaning frequency. Cordovan lasts longer due to fibre density. Ageing is not deterioration: the patina developed testifies to the bond between owner and timepiece.

The next step

The right strap isn't chosen. It is built, together.

From the atelier appointment to delivery, every step is made for those who know that things done well take time. Rare leathers, one piece at a time, eighteen months of warranty.
