Omega Seamaster 300M Professional Diver Mens Full Size Watch, Stainless Steel -


Item No. ED01

Today's offering showcases this Certified Pre-Owned Omega Seamaster 300 Professional watch in mint condition.

Stylish and useful, it was inspired by the so-called James Bond watch, so named from when a Seamaster 300 Professional watch first appeared in the movie 'Golden Eye' (1995).

It is the full size version. Its large case measures 41mm in diameter without the crown and guards, larger than a Rolex sports model.

Its large luminous hands and hour markers against its black dial make it easily legible at all times, and the rotating bezel and helium escape valve are designed for true diving uses. It was originally designed to be water resistant to 1,000 feet.

It has a quick-setting hour for easy changing of the time zone and date.

Powering the watch is its original Omega Caliber 1538 precision quartz movement with end of life battery indicator.

In its pre-owned form, it's an excellent value, providing greater quality and attention to detail than is often found in watches in this $3000 price range.

It is all original and in gorgeous condition - it presents as about a 9.8 out of a perfect 10. The original bezel insert, which often shows the most wear on these, is virtually flawless. You won't be disappointed.

Our Master Watchmaker has performed any needed servicing including replacing the battery and replacing the waterproofing seals with new genuine Omega gaskets making it ready for immediate enjoyment.

Included with the purchase is a one-year C.O.T. international warranty on the movement and its function and a full-page custom printed Connoisseur of Time Certificate of Authenticity.
