The 42mm choice has expanded again! along with several other options Puretime and other vendors are now offering the PAM 337 O Radiomir, a 1940 case and golden hands mark the dial while the Seagull movt. used in the new PAM 512 completes the watch.

There seems to be a bit of confusion amongst the vendors as to the model, some call it a 338 while PT gets it right, with a SS case it is indeed a 337. The 338 is the same watch but with a Titanium case and every picture post I have checked shows a Stainless case despite the differing model number.
I have placed an order and will post my thoughts once it arrives.
