1970’s CLINTON World Cities GMT 20ATM – Automatic 25j Ronda-Matic Cal. 1239


Out of stock

Lovely big-case automatic, this is a classic model from CLINTON, with an automatic Ronda-Matic Cal. 1239 movement with 25j. The unpolished stainless steel case is in great condition and measures in at 40mm or 43mm including the crown at 3h [the original caseback sticker is still on the watch]. The dial, blue ring and hands are also in great condition. The mineral glass is the original one and we have decided to keep it to safe-guard the water resistance of the watch. It does show some scratches but nothing to distract. Wearing a NOS tropic strap from the same period [it might look a bit ‘white’ because we keep these in talk powder that maintains the rubber] and Localtime buckle [the high quality buckle is one of our own Localtime buckles, details and variations of which you can see in our eBay store, under eBay item number¬†400842595307], this fine timepiece has been professionally inspected and approved in-house here at Localtime. As with all the watches we inspect in-house here at Localtime, this one too will arrive to you with a 6-month written warrantee from the date of purchase. Feel free to contact us for whatever question you might have.
