Wow Chris be sure to post some photos when it arrives!
That movement looks, to me, a lot like an older ETA. So yes, the same as an older Tudor. I keep telling people that old dive watches are the way to go. They're loaded with good parts and you can get buckets of them for a song. The hard part is being choosy and being willing to pass on something as gorgeous as this Squale!
But next time a Jenny 1000 comes along for less than the price of a lung... don't get in my way!
PS: Hi Euno! Let's see some divers!
