Obligatory Wristwatch Thread

Looks like it’s discontinued now but there’s still some floating around. I decided on it to tide me over while saving for some grail watches. It’s pretty underrated as it uses the same case and parent movement (ETA 2893-2) as the Omega Seamasters. For about 20% of the cost. I wanted a GMT movement as our flight schedules were all written in UTC. Didn’t have to do math on the road.

BTW, still waiting on this one to be built

Very nice and Tots approves!! That’s almost the exact watch we have available for issue. I haven’t seen any commands actually issue it, but the Navigator Government model is the only watch listed in our flight equipment issue jacket. The only differences are the black colorway and the “US Government” script. I requested one last year but failed to follow up on actually getting it.

I wasn’t aware of the easy coin opening battery replacement on those, that is outstanding and still water resistant to 30m. That’s a great selling feature in my book.

Just a note about those 30 meters.

I don't know how Marathon tests its watches (go check please) but those numbers are often misleading because the depth they refer to mean to represent water pressure at that depth in calm waters. If you take a dive in the pool off the lower board, you will generate water pressure much higher than 3 bars (the nominal 30 meters) even if you go no further than 8 meters deep. Take that dive while wearing a 30 meters rated watch and expect to drown it.

In the watch world, a 30 meters depth rating generally mean you can wash your hands under a spigot but shouldn't take that watch anywhere near a body of water. Maybe Marathon does things differently but if you want a watch that will withstand the rigors of water a 5 bar rating minimum is required for surface swimming.

P.S.: 1 bar= 1 atmosphere = 1 meter of placid water.

The steel Navigator has the coin-slot battery hatch, and 100 meters of water resistance. And, 10 sec./year high accuracy quartz.

There are entire threads on WUS about whether 3 bar means swimming at 30 meters or not.

There was an Italian gent some years back, can't remember his name offhand, that started a long thread about all his dives with a 30 meter or something like that digital Casio. My recollection is he took it to recreational limits (130 fsw) and it held up fine. The dynamic pressure thing is pretty widely poopooed because we aren't moving at nuclear torpedo speeds. That being said, I only dive with actual dive watches so I don't give it much thought.

Check the conversion math here…

1 bar = 1 atm = 14.7 psia = 32.2 ft of water = 10 meters of water.

Thank you for correcting me.

I typed too fast and should have double checked.
