Q: What is the water resistance on this model and can I swim with it?
A: The Seamaster 120M is rated to 120 metres (12 bar). It is suitable for swimming and snorkelling when the crown is fully secured and the gaskets are in good order. Rinse in fresh water after sea use, avoid hot tubs/saunas, and have the watch pressure‑tested periodically—especially after a battery change or if you plan regular water use.

Q: Which movement does it use and how accurate is it?
A: This reference typically uses Omega’s quartz calibre 1538. It is highly accurate and features an end‑of‑life indicator: when the battery is low, the seconds hand jumps in four‑second steps while timekeeping remains accurate for a short period. Battery life is usually around 2.5–3.5 years, depending on use and temperature.

Q: Does it have a screw‑down crown?
A: Yes. The crown is screw‑down to help ensure water resistance. Always make sure it is fully secured before any contact with water.

Q: Is the bezel on this Seamaster 120M a rotating diver’s bezel?
A: No. Unlike the Seamaster 300M Professional, the 120M in this reference has a smooth, fixed bezel for a cleaner, more dress‑leaning look.

Q: What are the case size and fit like?
A: The case measures approximately 36.25 mm across, a versatile mid‑size that suits many wrists. This piece is currently sized to fit a wrist up to about 16 cm; links can be added or removed by a watchmaker for a custom fit.

Q: What is the lug width and can I fit other straps?
A: The lug width is 18 mm. You can fit most 18 mm straps, and this model commonly pairs with the Omega mid‑size steel bracelet (often referenced 1501/823). Always use quality spring bars and have strap changes done carefully to avoid scratches.

Q: Does the dial have lume for low‑light visibility?
A: Yes. The blue wave dial variant features luminous hands and hour markers for readability in low light.

Q: Is it okay to shower with the watch on?
A: We do not recommend showering or sauna use with any watch due to heat and steam, which can stress seals and cause condensation. For water activities, stick to cool or room‑temperature conditions and ensure the crown is secured.

Q: When was this reference produced and is it still in production?
A: The Seamaster 120M in this configuration was produced in the 1990s through the 2000s and is now discontinued. Pre‑owned examples like this one remain popular for their classic proportions and reliability.
