Up for sale is my lovely El Primero open chrono. Full specs of the watch can be found on the Zenith site: http://www.zenith-watches.com/en_en/...-1969-164.html These retail for around £7,250 I think. 42mm and 50 hour power reserve. Comes with box but no papers other than an authentication card I received with the watch from the dealer. Watch is in great shape other than some marks to the bottom lugs that should come out with a light case refurbish. I've added a new strap but it's not a Zenith one as they were stupidly expensive. Very nice leather though and I obviously kept the original deployant and buckle. I don't know the age of the watch I'm afraid. The only issue with the watch is that it probably needs a service as the power reserve only keeps to around 30 hours or so (from memory) although it is keeping time well (+13s). I did arrange for a repairer to do this for me as he can obtain the relevant parts but I am of course looking to move it on and will leave the new owner to decide what to do with it. I'm looking for £3,500 £3,400 £3,300 by BT inc delivery within EU. Can discuss options outside of this. I have lots of references available over at TZ-UK on the Heroes & Villains board (same username). Any questions, please let me know. Thanks, Steve
