FS: REDUCED: Zenith XL-Tronic Tuning Fork, near mint

Price reduced to EUR 470,- for this humming vintage beauty. Furthermore, there is a temporary possibility to purchase an unused (new old stock) Zenith mesh bracelet (i.e. the contemporary alternative to a leather strap for this particular model) for an additional EUR 100,-, thus making this a perfect set with two signed strap/bracelet options.

=======================================================================================================

I guess it’s no exaggeration to claim that any serious vintage watch collection is incomplete without at least one tuning fork controlled watch. So here’s a chance to grab one in outstanding condition, namely this beautiful Zenith XL-Tronic vintage gem from around the early/mid 70s. (To be precise, the Zenith logo used on the dial was first introduced in 1973 and the Mosaba calibre ETA-ESA 9162 (Zenith 50.0) was only manufactured until 1976. That's how far I can narrow down the possible year of manufacturing.)

Case – Tonneau shaped all stainless steel case (36mm wide without / 38mm wide with crown, 41mm lug to lug, 19mm lug width) in excellent original condition (unpolished, not refinished) with perfectly sharp lugs and edges and only minor superficial marks on the polished sides. The original brushing is fully intact and actually looks as new. The beveled bezel is impeccable, the screw-down caseback shows a few very superficial marks but overall still is in very good condition. The signed crown (non-screwed) is all original. To sum it up, the case is very close to mint condition showing that this watch was not worn a lot over the past decades (as was also confirmed by its previous first and single owner).

Dial and hands – The elegant silver dial with vertical brushing pattern and the Zenith-typical date window is in superb condition, too, spotless and with a fine black minute track and silver indices. All 8 original lume markers are intact (there is no and has never been any markers at 3, 6, 9, and 12 o'clock) and the tritium has taken on a vanilla colour, perfectly matching on dial as well as the all-original slim handset.

Crystal – Scratch-free flat mineral crystal.

Movement – Zenith Caliber 50.0 (ETA-ESA 9162) tuning fork movement running on an impressive frequency of 300Hz. Consequently, the tuning fork emits a (gentle) distinctive humming sound and the second hand is gliding without any observable steps. The movement is running very precisely on modern button cell batteries (preferably of the type SR42 = 344) and the date changes as it should. A fresh battery was fitted, so the watch is ready for use. The movement’s service history (if there is any at all) is not known to me but the watch has been checked by a watchmaker in Q1/2021 with no need for service back then.

Strap and buckle – The watch comes on a brand new textured black leather strap with white stitches tapering from 19mm to 16mm. Moreover, a 16mm (inner width) vintage Zenith buckle with the same logo as on the dial and the crown completes the coherent look.

Price – Due to its outstanding all original and perfect technical condition I am asking EUR 490,-, plus shipping (e.g. fully insured shipping to the US approx. EUR 20,-).

Eventually, here come the pics (battery removed in movement pictures to show the corrosion-free battery compartment):

The watch is located in Austria (EU) and so am I. I do have plenty of international references from various watch enthusiasts (also known here), so please feel free to ask for them.

Just for the records: I am a private collector and, therefore, the watch comes without any personal guarantee given by me. Nevertheless, I am offering to give a full refund less fully insured shipping expenses in case the piece sold would not be as described by me (within an inspection period of three days and to buyers from within the EU only due to the complex customs procedure in case of an overseas deal).

Thanks for reading and thanks to the Chronotrader platform and its host!

Kind regards,
F.Antl
