The Speedmaster Reduced 3835.71.33 (aka: 38357133), seen from the bench

The Speedmaster Reduced 3835.71.33 (ref. 38357133) is a 39 mm stainless steel chronograph produced between 1998 and 2005, featuring the Omega 3220 automatic movement with column-wheel system. The watch combines the Professional's mechanical integrity in a more contemporary size, retaining the sapphire crystal, monocoronе, and sealed caseback. It features a black tachymetric bezel, black or champagne dial, and requires an 18 mm lug width strap that fits securely without forcing or gaps.

Frequently asked questions

What is the lug width of the Omega Speedmaster Reduced 3835.71.33?

The Omega Speedmaster Reduced 3835.71.33 has a lug width of 18 mm. This measurement is specific to this reference and must be respected when replacing the strap. To verify, use a digital caliper to measure the slot on the case.

What strap do you recommend for the Speedmaster Reduced 3835.71.33?

For this model we recommend a medium brown or cognac alligator, which creates an elegant contrast with the satin-finished steel and works in almost every context. A shell cordovan offers superior resistance and a captivating natural luster, while a vegetable-tanned calf in black represents the most versatile choice for aging and patina development.

How do you change the strap on the Speedmaster Reduced 3835.71.33?

Remove the watch from your wrist and place the case on a soft cloth with the lugs facing upward. If the strap is leather, use a sharp cutter to cut the stitching thread along the edges, starting from the inside. Once the thread is loosened, gently pull the strap from the lugs. To install the new one, thread it through the lugs following the natural angle and ensure it enters without forcing.

Are there aftermarket straps compatible with reference 3835.71.33?

Yes, all 18 mm straps are compatible with the Omega Speedmaster Reduced 3835.71.33. Milanostraps offers online a collection of customizable 18 mm straps in leather, color, and stitching thread. For a bespoke experience, Casati Milano also creates handcrafted straps with direct leather selection and 18-month warranty.

How long does a leather strap last on a watch like this?

A quality leather strap (alligator, cordovan, or calf) typically lasts 3-5 years with daily wear, provided minimal maintenance: avoid prolonged moisture and direct contact with salty sweat. Shell cordovan tends to last longer, up to 7-8 years, thanks to the compactness of its structure. Vegetable tanning ages more aesthetically than industrial methods, developing a desirable patina.
