I have been looking for a durable, affordable pilot watch in recent weeks, so I am considering modding a 120 case with a smooth bezel and 647 dial (looks closest to a traditional flieger dial IMO). I also love the domed crystal and 200M WR (which many pilot watches costing considerable more lack). And I can swap a diver bezel and put on the stock rubber strap to make it a dive watch.
What do you think? Here is a picture I found of a similarly modded 120 with a different dial. I would like to swap the hands, but Meranom does not appear to carry anything other than the standard Amphibian and Komandirskie handset.
