Today I'm selling my early Zenith Rainbow 53.0370.400 with the El Primero cal. 400. The 40mm 18k and stainless case looks stunning against the blue dial and bezel. Both crown and pushers screw down for water resistance. The original bracelet 20mm is sized to my 7.5" wrist and comes with an extra link. The original tag, card and booklets accompany the sale, as does a Zenith box but not the style generally associated with the Rainbow line. The watch keeps excellent time but has not been serviced in my care so it is recommended, given its age. Feel free to ask any questions. Please review the photos as they are integral to the description. I'm asking $3000.00 OBRO, Wire Transfer or PayPal F&F, 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.
