This is part of my "I just bought a grail so now I have to sell stuff" sale.
This is the awesome Marathon JSAR Jumbo High Torque Quartz on Isofrane Strap. There is plenty of stuff written on the net about this piece so I won't bore you with it here.
The Isofrane has had very little use and the original strap is unworn. Actually bought the watch a few years ago but it didn't make it into rotation, you will see that is in excellent condition with only light signs of use.
I have recently had my watchmaker change the battery so you should be fine for a few years..
It's a large watch but being quartz makes it feel quite light and the Isofrane is so comfortable and well balanced on the wrist.
Asking US$550 shipped just about anywhere from Australia. Please PM me with any questions.
