Frequently asked questions

What is the lug width of the Omega De Ville 424.57.37.20.55.002?

The lug width is 19mm. This unconventional measurement reflects the compact proportions of the 36.80mm case. To verify it, measure the internal distance between the two spring bars with a caliper: the result must be exactly 19mm. Do not confuse with 40mm De Ville models which require 20mm lug width.

What is the best strap for this white gold Omega?

Vegetable-tanned alligator represents the choice most coherent with the formal elegance of white gold. Black alligator creates the most formal pairing, while cognac-colored alligator introduces warmth for daytime contexts. Traditional calf leather in black or medium brown remains a valid alternative if you prefer greater initial softness.

How do I change the strap on the De Ville 424.57.37.20.55.002?

Obtain two tools: either a two-pronged spring bar remover or a curved pin. Position the watch with the case facing down, locate the spring bar (the small horizontal spring between the case and strap), press the pin on the protrusion to compress the spring, and remove the old strap. Insert the new one respecting the orientation. If you have doubts, ask for assistance from a local jeweler or contact Casati Milano for personalized guidance.

Is a 19mm aftermarket strap compatible with model 424.57.37.20.55.002?

Yes, any 19mm strap designed for wristwatches is compatible. Verify that the <a href="/pages/termine-glossario/misura-ansa">lug width</a> is certified 19mm by the manufacturer. Custom straps from Casati Milano are made specifically for this attachment, guaranteeing aesthetic perfection and durability.

How long does a leather strap last on this watch?

A quality alligator strap with vegetable tanning typically lasts 3-5 years of moderate to daily use. Durability depends on frequency of use, climate, perspiration, and maintenance. Keep the leather dry, avoid prolonged immersion, and apply specific balm every 12 months. A calf leather strap, being less dense, tends to last 2-4 years. Casati Milano offers an 18-month warranty and replacement services at reduced cost.
