Next up, this very nice, early, example of Taro Tanaka's Grammar of Design with chronometer movement. The unserviced by me, manual wind 4420A chronometer movement hacks and was running at +7 s/d, when last checked. The 36.5mm case(excluding crown) has a 18mm lug width, 43mm lug to lug. As you can see from the photos, the case is in excellent condition, with minor scratches and dings from 50+ years of wear and some wear to the crown, which I believe is an old replacement. The dial is in good condition with a few minor spots. The case back with gold lion medallion, is in excellent shape, given its age. Feel free to ask any questions. I'm asking $950 OBRO, Transferwise or PayPal (please add 4%), US shipping included. International shipping cost will be paid by the buyer. I have a lot of feedback, both here and on WUS, as efauser, and saguy43 on eBay. Returns accepted if watch is not as described. Not interested in trades.
