The Chronograph EP95002-BL, seen from the bench

The Excelsior Park Chronograph EP95002-BL is a contemporary interpretation of classic Swiss chronographs, faithful to post-war watchmaking tradition. The stainless steel case measures 38.90 mm in diameter with balanced proportions suited to functional chronography. The deep blue dial features three circular counters (hours, minutes, small seconds) recalling 1960s–1970s Zenith and Seagull chronographs. Powered by the Sellita SW510 BH b automatic Swiss movement, certified chronometer with 28,800 vph balance oscillation, ensuring certified accuracy. The 20 mm lug width is proportional to the case diameter and overall thickness, maintaining design elegance.

Frequently asked questions

What is the correct lug width for the Excelsior Park Chronograph EP95002-BL?

The lug width of the Excelsior Park Chronograph EP95002-BL is 20 mm. This measurement is specific to the model and represents a standard specification in mid-size chronograph constructions featuring a 38.90 mm case. Lug width is measured perpendicularly to the longitudinal axis at the junction point between the lug tube and case. The strap lugs (terminal attachment points) must present a minimum depth of 11–12 mm to ensure stability without risk of accidental slippage.

Which natural material strap do you recommend for this chronograph?

For the Excelsior Park EP95002-BL, we recommend an alligator strap with tight grain in dark brown or black satin, which emphasises the chronograph's austere geometry without competing with the dial visually. Alternatively, a vegetable-tanned calf leather strap integrates natural patina development and aesthetic ageing over time, developing caramel hues and noble creases. Both materials harmonise with Swiss chronograph heritage and require a satin stainless steel deployante clasp for optimal wrist fit.

How do you correctly change the strap on this watch?

Strap removal is accomplished by extracting the spring bars from the lugs using a dedicated spring bar tool. Position the watch on a stable surface, insert the tool beneath the bar from one side, apply gentle pressure to compress the internal spring, then withdraw the bar outward. Repeat from the opposite side. Insert the new strap by aligning the lug passages with the case holes, then reinsert the spring bars until you hear a characteristic click. Verify that the strap does not slip before wearing the watch. If your Excelsior Park features a deployante clasp, confirm that the new strap is compatible with this closure system.

Which aftermarket strap is compatible with the Excelsior Park Chronograph EP95002-BL?

All straps designed for 20 mm lug width are compatible with the EP95002-BL, provided the lug passages present a minimum depth of 11–12 mm and thickness compatible with the case holes (approximately 1.5 mm). On milanostraps.it you will find a complete collection of 20 mm straps in leather (alligator, calf, shell cordovan), NATO fabric, and technical rubber. Always verify the specific lug passage depth and total strap thickness to ensure optimal fit and stability.

How long does a leather strap last on a watch like the Excelsior Park?

Leather strap durability depends on tanning quality, usage intensity, and maintenance practices. A high-quality alligator strap with vegetable tanning can last 4–7 years with moderate daily use and regular care (cleaning with a damp cloth, limited water exposure). A naturally tanned calf leather ages visibly within 2–3 years, developing characteristic patina, yet remains functionally reliable for 5–6 years. A shell cordovan strap, owing to its rarity and elevated cost, can exceed 10 years if protected from extreme humidity and mechanical wear. To extend your strap's lifespan, remove the watch before aquatic activities, avoid direct heat sources, and apply specialist leather conditioner every 6–8 months.
