Omega Lady-Seamaster 29mm Ref 2371.21 1991 Watch

Q: What movement does this Omega Lady‑Seamaster Ref. 2371.21 use?
A: It is a quartz model with a date display. Many Omega quartz calibres feature an end‑of‑life (EOL) indicator; when the battery is low, the seconds hand typically jumps in four‑second steps to signal it is time to replace the battery.

Q: Is it safe to swim with this watch?
A: When new, this Seamaster variant was rated to 120 metres. As a vintage piece from 1991, water resistance cannot be guaranteed without recent pressure‑testing and fresh gaskets. We recommend avoiding water exposure unless it has been tested by a qualified watchmaker immediately after service.

Q: What is the case size and how is it measured?
A: The Lady‑Seamaster of this era is approximately 28–29 mm across, measured without the crown. Please refer to the Measurements on this page for the exact diameter stated for this specific piece.

Q: What is included with this listing?
A: This listing includes the watch only. Everything that comes with the item is always listed under the product information section on this page—if it is not listed there, it is not included.

Q: What wrist size will it fit, and can the bracelet be adjusted?
A: It is currently set to fit around a 16 cm wrist. The stainless‑steel bracelet can be adjusted by adding or removing links through a competent jeweller or an authorised Omega service centre. If you need guidance on sourcing extra links, our team can advise before purchase.

Q: What materials are used and how durable is it?
A: This reference features a stainless‑steel case, a gold‑tone bezel, a white dial with date, and a sapphire crystal that is highly scratch‑resistant. Normal daily wear is handled well; avoid abrasive polishing and harsh chemicals to preserve the finish.

Q: The bezel shows discolouration—can this be improved?
A: Light cleaning may help, but visible discolouration on a gold‑plated bezel usually requires professional replating to restore the colour. This is specialist work and may affect originality; many collectors prefer to retain original finishes. A reputable watch‑plating service can advise on options.

Q: How often will it need maintenance?
A: Quartz Omegas typically need a battery replacement every few years. Periodic servicing is recommended to renew gaskets and lubricants; have water resistance checked regularly, especially before any water use.

Q: Is this suitable for everyday wear?
A: Yes. Its compact case, robust steel bracelet and reliable quartz movement make it an easy, fuss‑free daily watch. As with any vintage piece, avoid moisture, hard impacts and strong magnets, and store it safely when not in use.

Q: How does A Retro Tale authenticate this watch?
A: Every item is rigorously vetted by our specialists using multi‑point checks of the case, movement, dial printing, fonts, engravings, materials and serials. We stand behind the authenticity of all items we sell and can share additional details or photos on request.
