Cal 2531

(c): Mars Mountain

ZENITH movement cal. 2531 from somwhere around 1964, 19 jewels manual subsecond movement. Based on cal. 2511, but equipped with a micrometric regulation system and a higher beat rate (21 600 vs 18 000). The power reserve holds a good 50 hours. This watch, model 220 S, is very accurate losing approx. a second per day.

Cal 120

(c): Mars Mountain

ZENITH movement cal. 120. Fairly common with 100 000 made between 1953 and 1962. This particular watch is made in 1961. Central sweeping second hand, 18 jewels manual wind. A special feature is the hack mechanism; the watch stops when the crown is pulled to time setting mode. This allows better precision when setting the time. Gold plated movement with incabloc shock proofing.

The dial has seen better days and the stem is broken. The minute and seconds hand touch preventing the watch from running very long. The plastic crystal has tiny cracks. Beautiful movement, but this one goes into the drawer for now.

Cal 88-5-T

(c): Mars Mountain

ZENITH movement cal. 88-5-T. Manual ladies' size caliber made in 12 000 pieces in 1964. The base caliber 88 was made in quite a few different flavours, with a total count of almost 400 000 pieces. This makes the 88 a very common movement in Zenith's ladies' watches from the golden age of swiss watchmaking.

Ladies' watches doesn't hold much value today compared to similar gent's watches. These microscopic movements are more difficult to repair which makes them go into the dustbin when they break or dry up. So, if you are interested in collecting some extreme pieces of micro mechanics you should go for ladies' watches.

I got this one for my wife (almost for free but don't tell her that!), and I'm very happy to see that she wears it regularly. I like the classic clean looks of the steel case and brushed steel dial.

Cal 120T

(c) Mars Mountain

ZENITH manual movement cal. 120T. Basically the same as cal. 120, but it is fitted with a mobile stud holder, which helps centering the transmission stone. Cal. 120T is also nickel plated instead of gold. A special feature is the hack mechanism; the watch stops when the crown is pulled to time setting mode. This allows better precision when setting the time. 18 000 movements with this caliber was made in 1961-1963, this watch was finished in 1962 according to Zenith.

I love the simplicity of the black dial on this watch. I believe the dial might have been redone at some point. The watch runs and holds time well, and I got a new crystal fitted to really make it shine.
