Basic information

The two watches are very similar, but they have a few key differences. The movement of 16710 is more advanced and allows user to move hour & GMT hand independently. The 16700 works like any other watch, except GMT hand completes a single revolution in 24h timespan.

In addition to the functional differences due to the movement, there are other differences. 16700 was never offered with a SEL bracelet, and its manufacturing stopped at 2000 and 16710 came with two movements.

Personal Preference

For me, despite the fact that I own a 16700, the best combination is 2001-2003 GMT Master II because:

  • Superluminova
  • SEL bracelet
  • Lug holes

Fake Vietnam / Military Watch

There is a well known fake vintage watch that is persistently used to con newbies into thinking they have hit the jackpot. The dead giveaway is the reference Y22668 and the number 10589463. If you find this blog post by googling those numbers, the watch in question is a fake. None of these watches are authentic or contain a single original part.

Conclusion

There is a slim possibility that a legit vintage military watch exists somewhere with Y22668 and 10589463 stamped on the back. However, if Google brings you here with these numbers, the watch is most likely a fake. The brands are at least Patek Philippe, Rolex, IWC, Omega, Tudor and Breitling.

Interestingly there are few variations of the Rolex with seemingly random numbers. It may be that in later evolutions the manufacturer has switched to random numbering so that the watches aren’t easy to find by Google in blog posts such as this
