Frequently asked questions

What is the exact lug width of the Omega Speedmaster (Non-Moonwatch) 324.55.38.50.60.001?

The lug width is 18 millimetres. It is measured from the inner right shoulder to the inner left shoulder of the lug, excluding any decorative relief. This dimension is a construction specificity of the 38mm model and determines compatibility with aftermarket straps.

Which strap material best pairs with the Moonshine Gold of this Speedmaster?

Deep black alligator or medium brown represents the canonical choice: the natural texture and patina over time dialogue organically with the warmth of gold. Vegetable-tanned calf offers a sober and compact alternative. Avoid light shades that would complicate the visual balance of the luminous case.

How do you change the strap on the Omega Speedmaster 324.55.38.50.60.001?

Strap change requires extraction of the lug pins with a dedicated tool (spring bar tool). Position the watch with the upper lug facing upward, apply slight downward pressure on the pin to disengage from the groove, extract. Repeat for the lower lug. The operation requires care to avoid scratching the Moonshine Gold case.

Are there compatible straps readily available online for the 324.55.38.50.60.001?

Yes. Milanostraps.it offers 18mm straps ready for shipment in various materials (alligator, calf, shell cordovan, rubber), customisable in lengths, initials and stitching thread colour. It is also possible to commission a bespoke artisanal strap from the Casati Milano atelier.

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

A quality leather strap (alligator, vegetable-tanned calf) typically lasts 3-5 years with daily use, extendable to 7-8 years with rotation (alternating with other straps 2-3 times a week). Critical factors are: direct sun exposure (accelerates oxidation), constant humidity (generates mould), lug pressure. Casati Milano warranty covers 18 months against manufacturing defects.
