I am selling my rather rare vintage Wyler Dynawind Heavy Duty 660 (now there's a mouth full!!). It is in perfect working order. The upper crown works the inner rotating bezel, which moves ever so smoothly and has a stunning mid blue colour with great patina. The case size is 39mm in diameter without the crowns, lug space is 19mm. There are NO BOXES OR PAPERS. The case has a super sunburst pattern but there are some marks at the outside of the "7"o'clock lug (see first pic) but nothing terrible. I am looking for USD600 to include registered post delivery (plus 3% for paypal). NO TRADES PLEASE. I have references on WUS under the user name ray120d4. Genuine inquires will be replied to.
