The case measures 36mm in diameter without the crown and guards, 40mm with them. This midsize Seamaster 300m is well-suited for those with average size wrists.
Its large luminous hands and hour markers against its black dial, which appears blue through the sapphire crystal, 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.
In its pre-owned form, it presents an excellent value, providing greater quality and attention to detail than is often found in watches in this under $2500 price range.
It is fully Omega and presents in gorgeous condition - a 9.7 out of a perfect 10. Our photos couldn't begin to do justice to its condition. The case presents as perfect mint. Its dial is mint. Its crystal presents as mint. And its long, adjustable bracelet has only very mild stretch.
A Master Watchmaker has performed any needed servicing. For the finishing touch, we have meticulously detailed it making it ready for immediate enjoyment.
Included with the purchase is a one-year warranty on the movement and its function and a custom printed Connoisseur of Time Certificate of Authenticity.
