Materials and Specifications
The case is machined from 316L stainless steel, polished on the flanks and brushed on the lugs to mirror the original contrast finishing. Diameter sits at roughly 39.7 mm with a thickness near 13.5 mm and a 19 mm lug width, so it wears close to a vintage Speedmaster on most wrists. The dial uses a matte base with printed indices, luminous-filled hands and recessed sub-dials, while the hand-wound movement carries a power reserve in the region of forty hours. Pushers are firm with a clean reset, and the crown seals against dust and light moisture.
Shipping and Returns
Orders ship free with tracking and discreet, unbranded packaging, typically leaving the warehouse within a couple of business days. Delivery windows vary by destination, and every parcel includes a movement warranty plus a straightforward return window if the watch is not right for you. Keep the tags and presentation box intact to make any exchange simple.
Is the Cal 321 copy good for daily wear?
Yes. The compact case, slim profile and hardened crystal make it easy to wear under a cuff, and the splash-resistant build handles normal daily exposure without fuss.

How close is it to the original Speedmaster?
Visually it follows the vintage reference closely, from the step dial and alpha hands to the twisted lugs and tachymeter bezel. The movement architecture is inspired by the column-wheel Calibre 321 rather than a licensed original.
Does it have a display case back?
It does, which lets you see the column-wheel chronograph and decorated bridges. If you prefer the solid steel back of the earliest references, check the listing options before ordering.
