Strap for LadyMatic Co-Axial 34 Stainless Steel / Red Gold / MOP / Bracelet

The lug width of the 425.20.34.20.55.001 model is 20mm. This measurement, expressed as the center-to-center distance between the two lugs of the case, is the standard construction specification for Omega ladies' timepieces. It is essential to measure this distance before ordering aftermarket straps, as undersized straps (18mm) would be excessively loose, while oversized ones (22mm) will not fit into the attachments. Milano Straps offers a specialized collection of 20mm straps compatible with this model.

The choice depends on usage and personal preferences. Cognac brown alligator represents the classic choice, as the fine texture and warm tone naturally resonate with the Red Gold case, creating chromatic harmony. Bordeaux shell cordovan is ideal for those seeking exceptional durability and sophisticated patina: equine leather resists daily wear for 10-15 years and develops a characteristic cognac tone over time. For summer months, champagne or sand alligator introduces a lighter palette. If you prefer versatility, a cotton NATO allows quick changes without tools. The Casati Milano atelier creates bespoke straps following personal consultation on your taste and lifestyle.

The strap on the 425.20.34.20.55.001 model is secured with standard bayonet spring bars. Using a spring bar tool or a flat non-abrasive object, apply gentle pressure inward on one of the two lateral lugs of the spring to make it retract, then extract the spring and old strap. Insert the spring into the new strap by aligning the two lateral holes, then position the spring in the case attachments, pushing gently until the locking click. Repeat the same procedure on the other side. If you prefer to avoid DIY, the Casati Milano atelier offers strap change service with aesthetic consultation and damage warranty.

Any strap with exactly 20mm lug width is constructively compatible with the 425.20.34.20.55.001 model. Milano Straps offers a specialized collection of 20mm straps made from authentic alligator, vegetable-tanned calf, shell cordovan, and NATO fabrics. All straps come with standard bayonet spring bars and adjustable keepers. You can order online with customizations such as specific length for your wrist, monogram initials, and choice of stitching thread. The Casati Milano atelier also creates bespoke straps to measure following telephone consultation or in-store appointment.

Longevity varies significantly based on material and usage. A quality alligator or calf strap, with moderate daily wear (worn 3-4 days per week), maintains structural integrity for 5-7 years. Shell cordovan, thanks to the exceptional density of equine leather and natural resistance to wear, can last 12-15 years under the same conditions. NATO fabric straps resist wear indefinitely, except for aesthetic wear. The bayonet spring bar maintains functionality for decades if not subjected to repeated stress. Milano Straps supplies all straps with an 18-month warranty against manufacturing defects. To extend the life of your leather strap, it is advisable to use two straps in rotation and treat them periodically with protective balm specific to luxury leather.
