This unworn XL-Tronic is potentially the best in the World.  Original strap, buckle and hangtag. Model reference 01.0030.510

HOW DO WE DATE THIS WATCH?

From the logo and model number system we know it is post 1970.  The movement used in this watch was first launched at the Basel fair in 1972.  Manfred Rossler features a XL-Tronic in his excellent book on Zenith watches, and that is labelled circa 1973.  We think our watch is the same vintage as the one featured in the book.  So confident were Zenith in the new quartz technology that by 1975 they suspended making all mechanical movements, and only made quartz regulated watches.

CONDITION

How many better examples could you hope to find?  These early quartz watches are becoming really popular, due to their size (more in keeping with modern tastes) and the ease of ownership.  The very first quartz watch was only launched in late December 1969, so this was cutting edge technology and was not cheap.  Some XL-Tronic Zenith’s had hummer movements, but this has the Zenith calibre 51, which is a rebadged ESA 9180 – the first ETA quartz movement ever.  Unlike the earlier Beta21 calibre, which was the first Swiss Quartz movement, this movement runs at 32,768Hz, like almost every quartz watch since Girard-Perregaux introduced it as the standard.  Everything is working as it should.  The case is great, as is the glass.  The case has light marks from being stored without a box, but the graining is superb.  The dial has a fade from almost purple in the centre to lighter blue on the edge.  The leather strap is the original one, and has some signs of fading but is otherwise excellent.  The buckle is the signed original, and has the hangtag (with the correct model number).  We will install a brand new battery before sending the watch out to the new owner.

This watch will be supplied with our branded presentation box and our Certificate of Authenticity.
