Frequently asked questions
What is the lug width of the Omega Trésor 428.58.26.60.04.003?
The lug width of the Trésor 428.58.26.60.04.003 is exactly 13mm. This measurement must be verified with a digital caliper or ruler between the inside of the two lugs of the case. Any strap ordered must be compatible with 13mm to ensure proper fit without lateral play.
Which strap materials pair best with this model?
Natural alligator with constrained grain and satin finish is the most sophisticated choice, enhancing the geometric elegance of the Moonshine Gold case. For daily wear, vegetable-tanned calf offers authenticity and develops a patina over time. High-density rubber straps remain excellent for practicality without aesthetic compromise. Avoid overly vibrant color tones: the strap should dialogue with the gold, not visually compete.
How do you change the strap on the Omega Trésor 428.58.26.60.04.003?
The strap is changed by extracting the lug pins (spring bars) using a dedicated tool, such as a pin extractor or small screwdriver. Position the pin from outside toward inside to release the internal spring, remove the strap, and insert the new one by aligning the holes. Apply uniform pressure until the pin clicks into position. If you do not have the proper tools, it is advisable to consult a professional.
Are aftermarket straps available for the Trésor 428.58.26.60.04.003?
Yes, Milano Straps offers online a complete collection of 13mm compatible straps, customizable in sizes, initials, and stitching thread. All straps are handcrafted with certified quality materials. For a bespoke experience with personal leather selection, consultation, and 18-month warranty, the Casati Milano atelier offers an appointment-based service with fully tailored execution.
What is the average lifespan of a leather strap for this watch?
A quality leather strap with vegetable tanning, worn daily, has an average lifespan of 3-5 years before requiring replacement due to natural wear of the buckle or leather. Premature aging accelerates with constant exposure to moisture and perspiration. Natural alligator straps, being denser, offer superior longevity of up to 7-8 years. Regular maintenance (drying after water contact, treatment with specific creams) significantly extends the strap's lifespan regardless of material.
