The Heritage

The Excelsior Park Chronograph EP95004-BL is a 38.90 mm chronograph powered by the Sellita SW510 BH b automatic movement with chronograph function. The stainless steel case features a brushed satin finish, while the 20 mm lug width defines its proportional design philosophy. This model reconciles classical sports chronograph aesthetics from the 1960s–1970s with contemporary precision standards, rejecting oversized proportions in favor of balanced wearability.

FAQ

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

The Excelsior Park Chronograph EP95004-BL features a lug width of 20 mm. This dimension is critical for strap compatibility: a 20 mm strap will attach perfectly to the two lateral lugs of the case. Incorrect measurement would result in purchasing incompatible straps. To verify precisely, use a digital calliper positioned perpendicularly to the case, measuring the distance between the two lower attachment points.

What type of strap is most suitable for the Excelsior Park Chronograph EP95004-BL?

The Excelsior Park EP95004-BL chronograph, with its vintage language and satin steel finish, pairs excellently with premium leather straps (alligator, vegetable-tanned calf), NATO canvas for emphasising sporting character, or FKM rubber for dynamic contexts. A cognac-brown calf strap creates natural chromatic harmony; black alligator proposes maximum sobriety; beige NATO maintains vintage narrative. Choice depends on intended usage and desired wearability context.

How do you change the strap on a 20 mm lug width watch?

Strap replacement occurs through spring bars that traverse the lugs vertically. Use a specialised tool (spring bar tool) to extract the bars, releasing the worn strap. Position the tool in the small lateral hole of the bar, apply gentle pressure and withdraw. Subsequently, align the new 20 mm strap to the two lateral case lugs and reinsert the bars using the same tool until fully secured. Verify attachment by gently pulling the strap.

Can I use an aftermarket 20 mm strap on my Excelsior Park EP95004-BL?

Yes, provided the strap is strictly 20 mm. Artisanal aftermarket straps permit infinite customisation: choose leather type (alligator, shell cordovan, vegetable-tanned calf), colour, edge finishing, and buckle type (ardillon, deployante). Ensure the lug width corresponds exactly. Milanostraps offers a curated selection of 20 mm compatible straps, ready for dispatch or customisable according to specific chromatic and material requirements.

What is the average lifespan of a leather strap on the Excelsior Park EP95004-BL chronograph?

Leather strap durability depends on material type, usage intensity, and climatic conditions. Vegetable-tanned calf lasts approximately 3-5 years with moderate daily use; alligator can exceed 5-7 years due to greater fibre density. FKM rubber maintains structural integrity up to 7-10 years. NATO canvas strap lasts 4-6 years. Determinant factors: avoid prolonged moisture exposure, dry after aqueous contact, occasionally apply protective balm to untreated leathers. Conscious maintenance significantly extends useful life.
