With some regrets... Selling my: Zenith A273 manual wind chronograph. From the late 1960s. Uses Martel movement, Zenith calls it caliber 146HP. 37mm diameter (not including the crown). 44mm in length and 11,5mm height. Lug width 19mm. The blue strap on the photos does not come with the watch, because it's sold. It's the strap of the Heritage 146 Zenith. But, I do have other straps. I can give away the brown racing strap made by Joseph Bonnie. It's really good! CONDITION I think the watch is in good condition even when it has some scratches and marks here and there. Most importantly the dial looks good. It has some little flaws as you can see from the photos. I personally like this clean and classic timeless design. The case is pretty good. The subregisters' hands are blued and it shows under certain light angles. One hand is more lilac. HOW DOES IT RUN? Keeps time well. I haven't measured precisely, but surely +/- 20 sec. I can time it. The chronograph runs well and resets. Sometimes hour totalizer wants 2 pushes to reset to zero. I don't know the service history. Pushers work nicely and the crown turns smoothly. A fresh video I took 22th September 2020: I do have more videos under my channel. PRICE / SHIPPING 3200€ + shipping. That is the lowest price in the current market. I have used DHL Express that ships in 1-2 business days to anywhere. I am not sure if I can insure it to the full price. I am not a dealer. Parcel Pro does not work in my country. I prefer bank transfer. The buyer pays the fees. ABOUT ME I am located in Estonia, EU. I have plenty of good feedback here (search my name) and on eBay. I have many nice photos on my Instagram about this watch and others I have (or had).

I've taken many great photographs of it and worn it on many special occasions. But, I feel that I need to move on. Some Omegas need my money (caliber 32x). I don't keep every watch, because can't afford so many. Thanks OF! From this photo, the Heritage 146 is not included! I just wanted to share this image to show the comparison with a modern Z and how nice the strap is.
