The Heritage

The Excelsior Park Chronograph EP95001-BL is a 38.90 mm stainless steel chronograph featuring a blue dial and matte black finish. It is powered by the Sellita SW510 BH b caliber with complete chronograph functions including hours, minutes, small seconds, and true chronograph. The case maintains classical proportions typical of traditional chronographs, with satin stainless steel that dialogues naturally with the blue dial. The 20 mm lug width is dimensioned to maintain visual balance with the 38.90 mm case, avoiding disproportionate sizing.

FAQ

What is the lug width of the Excelsior Park Chronograph EP95001-BL?

The lug width (also referred to as strap width) of the Excelsior Park Chronograph EP95001-BL is 20 millimetres. This width was specifically engineered to maintain visual balance with the 38.90 millimetre case diameter. You can verify your lug width by measuring the distance between the two horizontal lugs that connect the case to the strap.

Which strap is best for the Excelsior Park Chronograph EP95001-BL?

The ideal strap depends on your intended use and aesthetic preferences. For formal contexts, alligator with fine grain delivers constructive elegance. For daily versatility, vegetable-tanned calf develops natural patina over time. For sporting interpretation, cotton NATO emphasises the chronograph character. For technical and operational application, structured rubber represents the most appropriate choice.

How do I change the strap on the Excelsior Park Chronograph EP95001-BL?

Strap replacement is accomplished by removing the spring bars (horizontal pins) that connect the case to the lugs using a dedicated spring bar tool. Once removed, the old strap slides away naturally. Align the new 20mm strap's eyelet holes with the lugs, then reinsert the spring bars through both the lug holes and strap eyelets. If you lack experience, consult a professional to avoid case scratching.

Which aftermarket straps are compatible with the Excelsior Park Chronograph EP95001-BL?

The EP95001-BL accepts any strap featuring a 20-millimetre lug width. This includes alligator, calf leather, shell cordovan, cotton NATO, silk NATO, vulcanised rubber, and suede options. Compatibility is determined exclusively by lug width—no other factors restrict interchangeability. Always verify that strap thickness maintains proportional balance with the case diameter.

What is the lifespan of a leather strap on the Excelsior Park Chronograph EP95001-BL?

Leather strap durability depends on tannery quality, tanning method (vegetable or chrome), and usage intensity. A calf leather strap with vegetable tanning typically lasts 3-5 years under daily wear before replacement becomes necessary. Alligator straps may extend to 5-7 years. Chrome-tanned calf generally exhibits lower durability expectations. Natural wear progression includes patina development (vegetable-tanned leathers), fibre thinning, and structural weakening. Regular conditioning with natural oils and protection from excessive humidity significantly extends functional lifespan.
