With a 41mm steel case (water-resistant to 300m, of course), these are mostly cosmetic changes to the Omega Seamaster Diver 300M that is actually Omega’s entry-level mechanical men’s watch. As Bond helped make the NATO strap cool, this version appropriately comes on a five-stripe blue, red, and gray polyamide NATO strap, but it also comes with the five-link steel bracelet that is very much part of the Seamaster 300M’s character. The clasp has the Omega Replica Watches branding along with the 007 logo and even the “TM Danjaq” trademark.
Through a sapphire crystal case back, the rotor caries the Royal Navy’s Commander rank insignia (loop above two stripes) and winds the Omega Co-Axial 2507 COSC chronometer-certified movement. This is different from the standard production Seamaster Diver 300M’s caliber 2500 movement and solid case back.
The caliber 2507 has been used in other James Bond 007 limited edition Cheap Replica Watches, and I believe the main difference from the 2500 is found in its decoration – specifically, the “bullet” design in the center. You can learn more about the 2500 family of movements and how they compare to other Omega movements in our article here. The caliber 2500 movements are based on the ETA 2892, upgraded with Omega’s Co-Axial technology, and beat at an unusual 3.5Hz with a power reserve of 48 hours.
