This is no ordinary Submariner! This watch is from the rare series with a bezel engraved inside. ROLEX produced a Submariner with an internally engraved bezel for a short period. This makes it rarer and more valuable to collectors. The watch has been serviced and polished. Not worn after that. It's like new. I give 1 year warranty. Please look at the photos carefully. I will be happy to answer additional questions.
