A fake Speedmaster 40mm is a replica of the mid-size Omega Speedmaster, the chronograph that sits between the 39mm Reduced and the 42mm Professional on the wrist. If you want the Moonwatch look without the bulk, the 40mm case is the sweet spot: wide enough for a legible tri-register dial, slim enough to slide under a shirt cuff. This guide covers what the size actually means, how the specs compare, and what to confirm with any seller before you buy.
Key Features
- 40mm stainless-steel case with the classic twisted-lug Speedmaster profile

- Tachymeter bezel with a black insert and printed scale
- Sapphire or hardened mineral crystal with anti-reflective coating
- Automatic or quartz chronograph movement depending on the build tier
- 20mm lug width, so most aftermarket straps and bracelets fit straight on
- Luminous hour markers and baton hands for low-light legibility
- Deployant or fold-over clasp with a safety catch on steel-bracelet versions
Materials and Specifications
Most 40mm replicas use 316L stainless steel for the case and bracelet, with a polished-and-brushed finish that alternates along the flanks and lugs. Dial options usually run black, panda and blue, with applied indices and a printed minute track. Automatic versions typically house a 7750-derived chronograph calibre running at 28,800 vibrations per hour with a power reserve in the 40-hour range; quartz versions are thinner, lighter and less expensive to service. Case thickness generally lands between 12mm and 14mm, water resistance is usually rated to 30-50 metres, and the watch weighs roughly 130-150 grams on a full steel bracelet. Check the crystal type, the movement name and the stated water resistance before ordering.
Shipping and Returns
Orders are packed discreetly and dispatched with tracking, usually within a few business days, with delivery windows depending on your region. Unworn pieces in original condition can generally be returned within the stated window, so keep the packaging and tags intact until you have inspected the watch.
What does 40mm mean on a fake Speedmaster?
It refers to the case diameter measured across the case back, excluding the crown and pushers. At 40mm it wears noticeably smaller than the 42mm Professional but larger than the 39mm Reduced.
Is a 40mm Speedmaster comfortable for daily wear?
Yes. It suits wrists from roughly 6 to 7.5 inches and stays balanced on a bracelet or leather strap without overhanging the wrist edge.
How should I care for a replica Speedmaster 40mm?
Wipe the case with a soft cloth, keep it away from hot water and steam, and have the chronograph movement serviced if the pushers start to feel stiff or the reset fails to snap back cleanly.
