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

What is the exact lug width of the Wyler Vetta Jumbostar WV0405?

The Wyler Vetta Jumbostar WV0405 features a 20mm lug width. This measurement should be taken internally, between the two lateral spring bars connecting the strap to the case. Accurate measurement is essential to avoid play and instability when replacing the strap.

Which strap do you recommend for the Jumbostar WV0405?

The WV0405 adapts exceptionally well to multiple materials: an alligator strap with vegetable tanning emphasizes the sport-elegant character, while shell cordovan adds refinement with a patina that develops over time. For daily wear, a cordura NATO or vulcanised rubber strap offers superior tactile grip. We recommend neutral tones (black, dark brown, anthracite grey) that enhance the brushed stainless steel case.

How do you change the strap on this model?

The Jumbostar WV0405 uses standard spring bars. To change: remove the watch from your wrist, position the old strap on a soft surface, gently press the spring bar with a flat tool (specialized lever or the edge of a Swiss Army knife), extract the bar completely, align the new strap's holes, and snap the bar into position. The operation is reversible and requires no specialised tools.

Are compatible aftermarket straps available for the WV0405?

Yes, numerous high-quality aftermarket solutions exist for 20mm lugs. From specialised brands such as Hirsch, Barenia, and artisanal producers like Casati Milano, you can source straps in vegetable-tanned leather, Cordovan, certified NATO, and technical rubber. 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.
