Omega Speedmaster Reduced 3510.12 Description

Omega Speedmaster Reduced 3510.12 is a watch, inspected by our certified watchmaker in Geneva and offered by WATCHOYSTER. It ships worldwide, fully insured. The photos show the actual watch, and the sections below cover what matters when you choose between examples of this reference.

Condition and set

Any wear is visible in the photos, and we describe it as plainly as we can. Used (Very good) is the grade we assign after inspecting the case, dial, bezel, crystal, and bracelet, and the photos show the wear behind that grade. The set is described as "No original box, no original papers". Box and papers document provenance, and a watch with a full set is usually easier to resell.

The reference number 3510.12 separates this version from other variants of the model, down to dial, bezel and bracelet details, so match it against the photos before you buy.

Before You Buy Omega Speedmaster Reduced 3510.12

Key details about authentication, financing, viewing, delivery, and condition.

Yes. This Omega Speedmaster Reduced 3510.12 has been physically inspected in-house by our certified watchmaker, covering movement accuracy, case integrity of the 39 mm Steel case, Yellow dial condition, and overall authenticity.

If a watch does not display the financing badge, or its price exceeds CHF 10,000, interest-free financing is not available for that model.

For eligible watches, financing is available to clients residing in Switzerland, with terms from 3 to 24 months. Approval is typically completed within a few minutes during checkout by the HeyLight partner bank.

Please contact us via WhatsApp with the watch details, and we will confirm whether the model is available for viewing or collection only.

    I'm very happy with my purchase from Watchoyster. Although contact was a bit slow at times, perhaps because it was the weekend, all my questions were friendly answered. It was my first expensive purchase at Chrono24, so I was a bit unsure when my watch would be shipped. In the end, everything was handled smoothly within the agreed-upon timeframe, and I'm very happy with my purchase and with Watchoyster.

    The seller was extremely communicative from initial conversations through delivery. There was a minor issue on delivery that ultimately resolved itself; the dealer stayed in constant contact and introduced me to his watchmaker to ensure everything was functioning properly. Packaging was excellent and the outer box arrived in perfect condition; the interior box had a damaged corner, which the dealer acknowledged may have occurred before packaging. Overall I’m extremely happy with the purchase and my experience—would definitely recommend and buy from him again.
