Q: What is the Tissot PRX Powermatic 80 Ref T137.407.11.041.00?
A: It’s a modern Swiss‑made automatic watch with a 40mm stainless steel case, integrated steel bracelet and a blue dial. The PRX design revives Tissot’s late‑’70s aesthetic with a slim profile and refined finishing, paired with the Powermatic 80 movement for extended power reserve.

Q: What movement does it use and how long is the power reserve?
A: It uses Tissot’s Powermatic 80 automatic movement with up to approximately 80 hours of power reserve. Many examples feature a Nivachron balance spring for improved resistance to magnetism; we can confirm specifics for this piece on request. A Retro Tale includes a 12‑month mechanical guarantee with every watch.

Q: Is it water‑resistant and can I swim with it?
A: The PRX Powermatic 80 is typically rated to 100 metres when new. As this is a pre‑owned watch, water resistance cannot be guaranteed without recent servicing and pressure testing. We recommend avoiding swimming or showering unless the gaskets have been replaced and the watch tested. Always ensure the crown is fully pushed in before any contact with moisture.

Q: Does it have a sapphire crystal and a see‑through case back?
A: Most PRX Powermatic 80 models feature a scratch‑resistant sapphire crystal and a transparent case back showcasing the movement. If you’d like us to confirm these details for this exact watch, please ask and we’ll verify.

Q: How does the 40mm PRX wear—will it suit my wrist?
A: The integrated bracelet and slim case give the PRX a sleek profile that suits a wide range of wrists. Many find 40mm comfortable on approximately 15–19cm wrists, depending on personal preference. Share your wrist measurement and we’ll advise on fit and size it for you before dispatch.

Q: How do I set the time and date on the Powermatic 80?
A: With the crown pushed in, wind the watch by turning the crown (20–40 turns if it has stopped). Pull the crown to position 1 to quickset the date, and to position 2 to set the time. Avoid changing the date between approximately 8pm and 2am. After setting, push the crown back in firmly.

Q: Can the bracelet be resized or swapped for straps?
A: Yes—we can size the bracelet for you. This reference uses an integrated bracelet; straps or bracelets must be made specifically for the PRX 40mm to fit correctly. Additional PRX‑compatible straps are available from Tissot and specialist suppliers; contact us for guidance.

Q: What condition is this watch in and what’s included?
A: Overall condition: Very Good, with the hardware described as shiny with light scratches from normal wear. It’s a Full Set, delivered with original box, certificate, and the bracelet at full length (all links present).

Q: What accuracy and servicing should I expect?
A: Typical real‑world performance for Powermatic 80 is within roughly ±10–20 seconds per day, depending on wear and service history. A routine service every 5–10 years is commonly recommended, or sooner if you notice moisture, magnetisation, or timekeeping issues. Keep the watch away from strong magnets and have water resistance checked if you plan to use it around moisture.

Q: Is it authentic, and what are the purchase assurances?
A: A Retro Tale professionally authenticates every item. This piece is Swiss‑made and includes box and certificate as noted. We offer free, insured DHL shipping, a 12‑month mechanical guarantee, 14‑day full refund policy, and 0% customs fees for EU buyers. We own all watches we list.
