Frequently asked questions
What lug width does the Omega Speedmaster 38mm (324.58.38.50.60.001) have?
The Omega Speedmaster 38mm in Moonshine Gold (ref. 324.58.38.50.60.001) features a <a href="/pages/termine-glossario/misura-ansa">lug width</a> of 18mm. This width is specific to this model and is designed to visually proportion the case to the crown and dial. To verify it, measure with a caliper the distance between the inner edges of the two lugs: it should be 18 millimeters.
What is the best material for a Speedmaster 38mm strap?
It depends on the context of use and aesthetic preference. For formal elegance, we recommend natural <a href="/pages/termine-glossario/alligatore">alligator</a> in cognac tones that complements the Moonshine Gold, or polished black calf leather custom-made with initials. For daily wear and resistance, <a href="/pages/termine-glossario/shell-cordovan">shell cordovan</a> in bordeaux offers thickness and patina evolution over time. For modern sporting environments, a grey silver FKM rubber strap lets the pale gold take center stage.
How do you change the strap on this Speedmaster?
The 18mm lug width is replaced by removing the lateral pins (spring bars) that hold the strap to the case lugs. Use a spring bar tool or a small flat-head screwdriver: insert the tool into the space between the strap and the lug, push the pin toward the center of the case until it clicks, then extract it. Repeat on the other side. The new 18mm strap is installed by aligning the holes and reinserting the pins until they click into position. If inexperienced, consult a professional watchmaker.
Can I use an aftermarket 18mm strap on this watch?
Yes, as long as the strap is certified for <a href="/pages/termine-glossario/misura-ansa">18mm lug width</a> and the length dimensions are compatible (generally 80-120mm for the part worn on the wrist). We recommend verifying that the strap has a quality <a href="/pages/termine-glossario/deployante">deployante</a> if made of leather, to ensure stability and longevity. Milano Straps offers custom-made straps for this model with compatibility certification.
How long does a leather strap last on a luxury watch?
The durability varies based on material and use. A strap in quality <a href="/pages/termine-glossario/alligatore">alligator</a> or artisanal calf leather, with traditional or <a href="/pages/termine-glossario/concia-vegetale">vegetable tanning</a>, typically resists 2-4 years with regular maintenance (occasional cleaning, drying after exposure to moisture). <a href="/pages/termine-glossario/shell-cordovan">Shell cordovan</a> tends to last longer (4-6 years) thanks to its natural density. Lug breakage is often the first sign of wear. The Casati Milano atelier provides an 18-month warranty and recommends annual checks to preserve the strap.
