The Museum Collection 5777.71.56, seen from the bench

The Museum Collection N° 1 "Pilots 1938" Aquarella Aquamarine (ref. 5777.71.56) is a contemporary reinterpretation of Omega's historical archive, honoring over 170 years of watchmaking heritage from Bienne. The case measures 40.20mm in diameter, crafted in brushed stainless steel, and houses the Omega 2200 caliber with COSC certification. This model features a distinctive 24mm lug width, an unusual specification that requires specifically designed straps and ensures proper proportions between the case and bracelet.

Frequently asked questions

What is the lug width of the Omega Museum Collection 5777.71.56?

The lug width of the Omega Museum Collection 5777.71.56 is 24mm, a non-standard dimension that characterizes this model. This width represents a precise design choice to maintain correct proportions between the 40.20mm case and the strap. Always verify the case lugs to confirm compatibility before purchase.

What is the best strap for the Omega Museum Collection 5777.71.56?

The ideal strap is vegetable-tanned alligator leather, which develops a patina over time compatible with the brushed steel case and echoes the construction textures of vintage straps. Vegetable-tanned calf leather represents a valid alternative for those preferring softness, while NATO straps are recommended for those seeking sportive versatility.

How do I change the strap on the Omega Museum Collection?

The strap is replaced using a dedicated tool (spring bar removal tool) to remove the lugs from the case attachments. Gently insert the tool into the lateral spaces of the attachments, lift the lug to free it, then insert the new strap ensuring that the pins are firmly secured. For those preferring not to perform the operation independently, the Casati Milano atelier offers a replacement service with personalized consultation.

Which aftermarket straps are compatible with the Omega Museum Collection 5777.71.56?

All straps in 24mm lug width are compatible. On milanostraps.it a dedicated collection of 24mm straps is available, made in alligator, calf, shell cordovan, rubber and fabric. Each strap is customizable in length, initials and stitching color to fit your wrist perfectly.

How long does a leather strap last?

A quality artisanal vegetable-tanned leather strap, such as those produced by Casati Milano, has an average lifespan of 4-6 years with regular use and proper maintenance. Longevity depends on factors such as frequency of wear, sun exposure, humidity and storage care. All milanostraps.it straps include an 18-month warranty against manufacturing defects.
