Q: What model and year is this Omega Seamaster?
A: This is an Omega Seamaster 120m, reference 2511.31.00, dated 1998 in the product information. It is a Swiss-made, pre-owned watch with a listed case diameter of 36 mm.

Q: Is this watch quartz or automatic?
A: This reference uses the battery-powered OMEGA calibre 1538 quartz movement, rather than an automatic movement. It does not require winding and includes a date display.

Q: What materials and dial colour does this model have?
A: Reference 2511.31.00 has a steel case and steel bracelet, a silver dial and a domed, anti-reflective sapphire crystal. Sapphire is highly scratch-resistant, but it is not immune to damage.

Q: What wrist size will this watch fit?
A: The bracelet currently fits a wrist measuring 16 cm or smaller. Four extra links are included for adjustment. The maximum wrist size after adding them is not specified, so please confirm the required fit before purchasing.

Q: What condition is this watch in?
A: It is listed in Very Good Condition, with light traces of use externally. The internal condition is also rated Very Good, while the hardware remains shiny with light scratches. These condition ratings do not confirm a recent service or battery replacement.

Q: What is included with this Full Set watch?
A: The product information lists a box, outer box, tag and spare links, with four extra links specified. Although the title describes it as Full Set, warranty papers and an authenticity card are not explicitly listed; please confirm their inclusion before purchasing if they are important to you.

Q: Can I swim with this vintage Seamaster 120m?
A: The model’s original water-resistance rating is 120 metres, or 12 bar. However, seals deteriorate over time, and no recent pressure-test result is provided for this watch. Do not assume it is currently suitable for swimming; have its water resistance professionally checked before exposing it to water.

Q: How long does the battery last?
A: OMEGA specifies approximately 42 months of battery life for this reference. The battery’s installation date and remaining life are not provided for this particular watch, so this is not a guarantee of how long its current battery will last.

Q: How should I care for and service this watch?
A: Wipe it gently with a soft cloth and avoid heavy impacts, strong magnetic fields and harsh chemicals. OMEGA recommends annual water-resistance checks and a complete service every five to eight years. The service history of this watch is not specified in the product information.
