Today's offering showcases this Certified Pre-Owned Omega Seamaster 300 Professional automatic chronometer watch in gorgeous condition. Our photos couldn't even begin to do it justice!

The case measures 36mm in diameter without the crown and guards, 40mm with them. This midsize Seamaster is well-suited for those with average size wrists.

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.

This is one of the few Seamaster 300M watches that comes equipped with an 18K white gold bezel.

Unlike the majority of these 300m's that have quartz movements, this watch is powered by Omega Caliber 1120 automatic movement officially certified as a chronometer that showcases the fine art of traditional watchmaking.

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

It has all of its original Omega and presents in gorgeous condition. Its bracelet has fairly mild stretch - otherwise, the watch presents as 9.7 out of a perfect 10.

NOTE: When the photographs were taken the 18K white gold bezel insert had a slight patina, from the watch sitting unused for a long time. That has since been mostly wiped off so that it presents as mint.

The case presents as mint. Its dial and crystal both are mint. The finish on its bracelet, which has fairly mild stretch, presents as mint.

A Master Watchmaker has fully serviced the watch which consists of fully disassembling the movement, carefully inspecting each part, replacing any overly worn components, reassembling and lubricating the movement, and extensive timing testing and regulation (a $595 value).

Like a brand new Omega chronometer, it continues to keep chronometer grade time in all five testing positions. 

For the finishing touch we have meticulously detailed it 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, a custom printed Connoisseur of Time Certificate of Authenticity, and a new timing certificate.
