Q: Can this watch be worn for swimming or diving?
A: The Seamaster Diver 300M line is designed with 300-metre water resistance, making it suitable in principle for swimming and diving. However, with any pre-owned watch, we recommend having the water resistance checked before regular water use unless it has been pressure tested very recently.

Q: What is the helium escape valve for?
A: The valve at 10 o’clock is a specialist feature intended for professional saturation diving, where helium can build up inside a watch during long periods in pressurised environments. Most owners will never need to use it in everyday life, but it is part of the Seamaster Diver 300M’s iconic design.

Q: What does “Full Set” mean for this watch?
A: In the pre-owned watch world, “Full Set” usually means the watch is offered with its original presentation items, such as box and papers. As contents can vary by watch and year, we recommend checking the product information for the exact inclusions supplied with this piece.

Q: Does the bezel rotate in one direction only?
A: Yes, Seamaster Diver 300M models use a unidirectional rotating bezel. This is a classic dive-watch safety feature that helps measure elapsed time and prevents accidental rotation in the wrong direction during timing use.

Q: How often should an Omega watch be serviced?
A: Omega recommends regular care, including periodic water-resistance checks and a complete service roughly every 5 to 8 years, depending on use and condition. If a pre-owned watch is running poorly or has an unknown service history, an earlier inspection may be sensible.

Q: What does “Very Good Condition” mean for a pre-owned watch?
A: “Very Good Condition” generally means the watch presents very well overall, with normal signs of careful previous use rather than heavy wear. Light surface marks can be expected on a pre-owned piece, but it should remain attractive and highly wearable.

Q: Is a 36mm Seamaster only for smaller wrists?
A: No. While it is especially popular with smaller and medium wrists, many collectors also choose the 36mm version simply because they prefer a lighter, more understated dive watch. It can suit anyone who enjoys compact watch sizing.
