Speedmaster Reduced 3534.74.00— lug 18mm

The Omega Speedmaster Reduced 3534.74.00 features a lug width of 18mm. This is the original and unique configuration for this model. The measurement should be taken from the inside of one lug to the inside of the other, using a ruler positioned horizontally. A measurement error would result in strap incompatibility: a 20mm strap will not fit, a 16mm strap will be loose.

The ideal strap depends on your intended use. For a formal approach, vegetable-tanned alligator offers intrinsic elegance and develops a natural patina over time. Textured calf is a versatile and durable choice. For those seeking character, a cognac shell cordovan creates a fascinating dialogue with the steel case. For summer, a NATO or FKM rubber strap keeps the chronograph proportionate and casual.

The Omega Speedmaster Reduced uses fixed lug pins. You will need a spring bar tool, an instrument that allows you to compress the internal springs of the lugs to extract them. Position the tool under the lug, gently push inward, extract the spring bar, and finally remove the worn strap. Installation of the new strap follows the reverse process. If you are not experienced, a professional watchmaker will complete the change in minutes.

Any strap with an 18mm lug width is compatible. On milanostraps.it you will find a curated selection of artisanal straps in alligator, calf, shell cordovan and other materials, all available in 18mm and customizable. Compatibility is guaranteed, but quality varies significantly between manufacturers: choose brands that guarantee precise finishing and traceable materials.

The lifespan of a leather strap depends on the quality of the material, the tanning method, and usage. High-quality vegetable-tanned alligator lasts 4-6 years with daily wear, often longer. Textured calf offers similar longevity. Shell cordovan, being naturally more resistant, can exceed 7-8 years. Factors such as sun exposure, humidity, perspiration, and regular maintenance significantly influence durability. Artisanal straps from Casati Milano include an 18-month warranty.
