The Chronograph EP95004-BR, seen from the bench

The Excelsior Park Chronograph EP95004-BR features a 38.90 mm stainless steel case with a Sellita SW510 BH b mechanical movement, chronograph function with column wheel, and 20 mm lugs. This model emphasizes unconventional proportions and purposeful design choices that distinguish it from standardized formats. The steel case develops a natural patina over time while maintaining oxidation resistance, and the specific 20 mm lug width is integral to the case's dimensional philosophy.

Frequently asked questions

What is the exact lug width of the Excelsior Park Chronograph EP95004-BR?

The Excelsior Park Chronograph EP95004-BR features a 20mm lug width. This specification is inherent to the model and derives from the 38.90mm case proportions. To verify compatibility, measure the distance between the inner lugs with a digital calliper: the value must correspond precisely to 20mm.

Which bespoke strap is most suitable for this chronograph?

We recommend a strap in vegetable-tanned alligator, which amplifies the anomalous dimensionality of the case and creates material hierarchy with stainless steel. Alternatively, textured Hermès calf offers mutable surface qualities and aesthetic compatibility. For daily wear, a cotton twill NATO ensures versatility without compromise.

How do I change the strap on my Excelsior Park Chronograph without damaging the case?

Use a dedicated spring bar tool extractor. Position it in the lateral slots beneath the closing spring, removing the pin with gentle downward motion. The pin must travel parallel to the lug shoulders, not diagonally. Insert the new strap by aligning the holes and reintroduce the pin until the locking spring clicks.

Is an aftermarket strap compatible with the 20mm lug width of the EP95004-BR?

Yes, any strap with 20mm lug width is mechanically compatible. However, aesthetic compatibility requires attention: verify that the keeper (the securing segment on the lugs) is proportioned to the 38.90mm case geometry. Straps designed for larger watches may appear visually oversized.

How long does a leather strap last on this chronograph?

A premium horology-grade leather strap (alligator or structured calf) typically lasts 3–5 years with regular use, depending on wear frequency, climate conditions, and maintenance. Vegetable-tanned leather ages gradually, developing organic patina. We recommend monthly rotation with alternative straps to extend lifespan and distribute wear.
