Strap for DS Eagle Chronograph Automatic

The Certina DS Eagle C023.727.37.051.00 features a lug width of 20mm. This measurement represents the space between the two case lugs and is identical on both sides. To verify strap compatibility, measure the gap between the lugs in the horizontal position: the value must correspond exactly to 20mm.

For the C023.727.37.051.00, we recommend three primary categories: structured leather in alligator or calf for transitions towards everyday elegance; NATO straps in technical fabric to emphasise the sporty and military character; vulcanised rubber for maximum practicality in humid and aquatic environments. The choice depends on intended use and desired aesthetic result. Milano Straps offers all these variants in 20mm, ready for immediate dispatch.

Strap replacement requires a specialised tool called a spring bar tool. Position the watch with the lug facing towards you, insert the thin blade of the tool into the small slot on the lug and gently lift the elastic pin. Once released, remove the old strap and insert the new one, pushing the pin until it clicks into place. If unfamiliar with the procedure, Milano Straps also offers a change service at the Casati Milano atelier, by appointment.

Yes, any strap designed for 20mm lugs is compatible with the C023.727.37.051.00. Milano Straps' artisanal straps are crafted to exact 20mm specifications and guarantee complete compatibility without need for adjustments. The quality of materials and Italian craftsmanship ensure longevity superior to industrial production straps.

The lifespan of a leather strap depends on usage and tanning method. A vegetable-tanned leather strap, subject to moderate daily use, maintains its structural properties for 3-5 years before requiring replacement. Prolonged exposure to sunlight, chlorine and salt water accelerates ageing. Minor patina and creases do not compromise functionality. Milano Straps exclusively uses high-quality leathers that age elegantly over time.
