The Heritage

The Excelsior Park Chronograph EP95004-PE combines vintage 1960s chronograph aesthetics with contemporary precision. This 38.90 mm stainless steel case with Sellita SW510 BH b movement operates at 8000–9000 oscillations per minute and features a dirty white dial with subdials for hours, minutes, and small seconds. The 20 mm lug width suits the 48.5 mm lug-to-lug distance, maintaining optical balance. Case thickness is 12.2 mm with transparent caseback and screw-down crown rated to 10 bar (100 m) water resistance.

FAQ

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

The lug width is precisely 20.00 mm. This measurement is critical as it maintains optical balance with the 38.90 mm case diameter. Always verify that any strap you purchase declares exactly 20 mm width, as even minor tolerance deviations will compromise proper fit at the lugs.

Which strap material is most suitable for the Chronograph EP95004-PE?

This depends on intended use. For formal and elegant everyday wear, alligator in vegetable tanning offers superior aesthetic harmony with the off-white dial and polished steel lugs. Cordovan leather provides a smooth surface that develops natural patina over time. For light sport use, FKM rubber guarantees full water resistance. NATO cotton canvas straps preserve the vintage chronograph identity whilst offering versatile styling options.

How do I change the strap on the Excelsior Park EP95004-PE?

The EP95004-PE features straight lugs with simple holes. To remove the strap, use a spring bar tool or smooth-tipped implement to push the spring bar toward the lug centre and slide the strap out. Insert the new strap by aligning the keeper hole, then gently re-insert the spring bar. Verify that the strap sits flush with the lug edges and has no lateral play. For very tight lugs, warm the lug area in tepid water to ease the strap passage.

Can I use an aftermarket strap from another 20 mm compatible model?

Yes, provided the width is precisely 20.00 mm. However, proper fit depends on keeper length and spring bar height specifications. The EP95004-PE uses standard straight lugs at 20 mm: any strap certified by Milanostraps.it for this measurement will be mechanically compatible. Before purchasing, consult the compatibility matrix provided with each strap to exclude structural conflicts with the case.

How long does a leather strap last on this watch?

Durability depends on material and frequency of use. An alligator or Cordovan strap in vegetable tanning, with moderate daily wear (4-5 days per week), retains structural integrity for 3-5 years before showing seam wear. Chromatic patina develops after 6-12 months of regular wear, enhancing aesthetic character. FKM rubber straps last 2-3 years under intense solar exposure, whilst NATO canvas requires frequent maintenance (cleaning) but endures 4-6 years with proper storage.
