Welcome to my Top Swiss Chronographs Boutique: Zenith SA is a Swiss luxury watchmaker. The company was started in 1865 by Georges Favre-Jacot at age of 22, in Le Locle in canton of Neuchâtel. Zenith has garnered more than 1,500 international watchmaking awards. Living legend among chronograph movements, the El Primero was introduced in 1969 as world’s first high-frequency automatic chronograph movement. Offered Chronomaster XXT: one of world's best watches; admire this impeccable mechanism, the sapphire case back allows you to enjoy the spectacle of finest watch art quality!

Distinctive design. Chic wooden heavy Zenith watch box (see pics). General professional pre-sale service was made in May 2024: the watch is keeping good time and working perfectly. Excellent condition, never worn: the wristwatch comes from luxury watch-shop showcase; that's why the strap is replaced with brand new one, leather straps often suffer from temperature in shop windows due to powerful spotlights. My personal authenticity and quality warranty: you will get warranty card (as pictured), fully completed and signed on the back. Insured, registered shipping worldwide with DHL Express: it’s not cheap, especially because of heavy massive watch box, and yet fast and reliable, two days in Europe, three days for the rest of this world. What you see in my pics is what you get. NO EXTRA COSTS for EU Buyers! Important info: I’m away for short vacation, will ship your watch on 02/07.
