Diy final version
My timer is set at about 6 hours and does not completely wind them up. $50.00 bucks worth of hardware.
There is a better chance the Hamilton will be more accurate out of the box. It has a solid movement and is steeped in history. The Seiko is just an improved Seiko 5.
They make a far smaller around 39mm gmt with that same movement also. That thing is a dinner plate with hands.....wow At the very least its a conversation piece.
Fine looking watch. Probably never see those in the North American market.
Gotta respect anyone brave enough to go into the vintage minefield and win doing it.
Hard to beat that one. Its an F91 on steroids.
A watch can survive a lot but longevity could be shortened because of it. The balance would be the weakest point even though it has shock settings. You can not argue with physics or gravity.
Where else on the net can people find you?
Tell the community a bit about yourself.
Let others know where you are and meet some local watch nerds!
