Offered for sale is the Sinn UX GSG 9 (EZM 2B), one of Sinn’s most purpose-built professional dive watches and the official service watch developed for the maritime unit of GSG 9. Constructed from German submarine steel, filled with oil using Sinn’s HYDRO Technology, and rated to an extraordinary 5000 m / 500 bar, the UX is engineered for extreme operational reliability rather than conventional luxury.

Presented in very good condition and true unpolished, the watch retains its original factory finish and all original parts. It is fitted with the original steel bracelet, suitable for wrists up to approximately 20 cm, or around 22 cm with the diving extension.

The watch comes with its Original Outer Box, Original Presentation Box, Original Strap Removal Tool, and our PW Certificate of Authenticity.

A major advantage is the recent authorized-dealer service completed on 16.10.2025 at a cost of €446, including oil replacement, new crystal, and full overhaul. This is especially important on the oil-filled UX, where proper servicing requires specialist handling.

With its crown at 10 o’clock, thermocompensated quartz movement, oil-filled display, and genuine GSG 9 operational heritage, this is a highly distinctive and technically serious Sinn tool watch.

All watches are shipped free of charge via DHL Express with full insurance. Dispatch is arranged within 0–2 business days after your payment has been received in our bank account. On average, delivery takes 1–2 business days within the EU, 2–4 business days to the USA, and 2–4 business days worldwide. The watch is located in the European Union (EU). Buyers are responsible for any duties and taxes for watches shipped internationally (outside the EU). We do not ship on weekends. For security, delivery is made only to the person named on the order. A valid ID and the tracking number, provided prior to shipping, will be required upon receipt.

Watches are eligible for return or refund within 14 days from the date the package is delivered. All returned watches will be thoroughly inspected for any signs of wear, tear, or damage. Any such signs may negatively impact the customer’s refund. Refunds are issued to the original payment method used at the time of purchase. All watches are delivered with a transparent protective tape and a secure seal that does not obstruct inspection of the watch. If the tape is removed or the seal is broken, returns will not be accepted. In the unlikely event that a return package goes missing during transit, insurance claims will be processed, and a refund will be issued only upon completion of the insurance claim.

Every timepiece from PASHA WATCHES is backed by our commitment to quality and authenticity. We provide a one-year limited warranty on all pre-owned watches and a six-month limited warranty on vintage timepieces (over 25 years old).

Our warranty covers defects in materials and workmanship under normal use. It does not cover water or moisture damage, natural wear and tear, accidental damage, or issues caused by misuse or improper handling. The warranty also excludes external components such as the bracelet, glass, dial, hands, pushers, crown, and bezel, as well as any work performed by unauthorized service providers.

While we take every measure to ensure reliability, water resistance is not guaranteed on vintage watches, unless explicitly stated in writing.

Every PASHA WATCHES timepiece is inspected, tested, and prepared by our certified watchmaker — ensuring lasting precision, authenticity, and peace of mind with your purchase.
