Q: Is this watch automatic or quartz?

Q: How long does the battery usually last?
A: Omega lists the battery life for calibre 1538 at around 42 months. It also has an end-of-battery-life indicator, so the watch should give notice when the battery is running low.

Q: Can I swim or shower with this watch?
A: The model was originally designed with 120-metre water resistance. However, as this is a vintage pre-owned watch, we recommend having it pressure-tested before swimming, showering, or prolonged water exposure, as water resistance depends on the current condition of the seals and case.

Q: How should I care for and service this watch?
