The Speedmaster (Non-Moonwatch) 324.15.38.50.60.001, seen from the bench

The Speedmaster Date 38 Stainless Steel (ref. 324.15.38.50.60.001) is a contemporary reinterpretation of Omega's chronograph lineage, featuring a 38mm stainless steel case with brushed sides and polished bezel. Powered by the Omega 3330 calibre with co-axial escapement and 18,000 vph, it combines racing heritage with refined proportions. The 18mm lug width maintains visual balance for the case diameter, while the column wheel chronograph ensures precise synchronization between pushers and counters.

Frequently asked questions

What is the lug width of the Omega Speedmaster (Non-Moonwatch) 324.15.38.50.60.001?

The Omega Speedmaster 38 324.15.38.50.60.001 has a lug width of 18mm. This width is specific to this model and ensures correct proportions between the 38mm diameter case and the strap. Any strap with 18mm lug width is compatible with this reference.

What type of strap do you recommend for the Speedmaster 38 Non-Moonwatch?

For the Omega Speedmaster 38 we recommend straps in alligator leather or vegetable-tanned calf leather, which emphasize the elegant character of the model. For a sporty profile, 18mm NATO straps in cotton or silk offer versatility. FKM rubber straps are ideal for summer. The choice depends on use: formal, daily, or sporty. Visit the collection of compatible 18mm straps to discover all options.

How do you change the strap on an Omega Speedmaster?

The strap is changed using a specific tool called a spring bar tool. This instrument allows you to compress the small metal springs (spring bars) that secure the strap to the case lugs. It is a simple and reversible operation that does not require watchmaking skills. Milanostraps provides detailed instructions with every strap. If you prefer, Casati Milano can assist you in our atelier.

Can I use an aftermarket 18mm strap on this Speedmaster?

Yes, any 18mm artisanal strap is compatible with the 324.15.38.50.60.001. Milanostraps offers a curated range of straps ready for shipment, customizable in color, initials, and stitching thread. For a completely custom strap (rare leather, double pass, bespoke details), the Casati Milano atelier creates artisanal straps with personal consultation.

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

A quality leather strap (alligator, calf, shell cordovan) lasts an average of 3-5 years with daily use, depending on the tanning process and frequency of wear. Vegetable-tanned leather ages more gracefully, developing a rich patina. Milanostraps offers an 18-month warranty on all artisanal straps. Wear is natural and desirable: the strap evolves chromatically, creating a unique patina on your wrist.
