Detailed Description
This reference is the modern evolution of the classic Seamaster Professional, with a 42 mm steel case, ceramic bezel, and laser‑engraved ceramic wave dial. The black ceramic bezel insert is highly scratch‑resistant and gives crisp contrast to the white diving scale, while the black wave dial adds depth and texture without sacrificing legibility. The date at 6 o’clock keeps the dial visually balanced, and the skeletonized hands and applied hour markers are filled with Super‑LumiNova for strong low‑light performance.
Inside, the Master Chronometer Co‑Axial movement brings anti‑magnetic construction, chronometer‑level accuracy, and a practical power reserve of around two days, making the watch easy to wear in a rotation. Paired with the stainless‑steel bracelet, it delivers the classic Seamaster tool‑watch feel, while the included black RubberB strap lets you quickly convert it to a more casual, sporty look for warmer weather or more active use.
Condition and Set
This 2025 Seamaster Diver 300M is in good overall condition:
Case shows light wear consistent with regular but careful use.
Clasp and caseback have visible marks/scratches, most noticeable under close inspection.
Bezel, dial, and sapphire crystals (front and back) present cleanly with no major defects noted.
Bracelet remains fully functional and cosmetically sound, with normal surface hairlines.
The additional black RubberB strap is included and offers a versatile alternative to the bracelet.
