I'm selling this Zenith El Primero chronograph: This is a later model of the first era (1974), ref. 01-0210-415, produced in a larger quantity, 4000 pieces according to Manfred Rössler. Dial, date disc, hands, and needles are in good, original condition. The hands were re-lumed recently. The crystal is flawless. The crown and the pushers are working perfectly. The case is in very good condition. It's surface is rather smooth. I don't know whether it was polished formerly. The dimensions of the stainless steel case are 36 mm * 40 mm excluding the crown. The height measures 13.3 mm, lug width 19 mm. The correct movement Zenith El Primero cal. 3019 PHC looks clean. The movement is running strong with rates between +4 s/d and +13 s/d at amplitudes from 245° to 272° and low beat errors. The chronograph is working smoothly and correctly. The watch is located in Germany/EC. I'm inviting offers around € 2,000, head only, payment by wire transfer, no Paypal. Cheers, Mick All photos were shot a few days ago.
