(Investigated in April 2022) *Conventional El Primero crown operation is different from a typical watch; the time is adjusted with 1 crown drawer, and the calendar is fast forward by pulling out 2 tiers, but with regard to this model (equipped with CAL.3600), just like a general watch, the calendar is fast forward with 1 tier crown drawer, and the time is adjusted with 2 drawers. Note, there is no description of the calendar fast-forward time period for CAL.3600, but just in case, please do not fast forward between 9:00 p.m. and 3:00 a.m. *White dial *The 3 o'clock in-dial is dull dark blue, the 6 o'clock in-dial is dark gray, and the 9 o'clock in-dial is light gray. *The dial indexes and hands are illuminated in the dark. *35 stone kifu seismic resistant device, flat beard, smooth temp, unique fine motion slow-speed adjustment device, column wheel type, with second hand regulation, 36,000 vibrations, 1/10 seconds, direct reading, can be measured up to 60 minutes *Unlike the previous El Primero, it is equipped with the so-called “Ethacron”. It has come to be seen by many manufacturers, probably because the ETA patent has expired. It seems to be a device that can efficiently adjust accuracy. *At first glance, it looks like a common three-counter chronograph, but in reality, it is a chronograph with a relatively complicated mechanism. Furthermore, as of 2022/4, the Zenith lineup has fewer types of traditional three-counter chronographs equipped with a 12-hour totalizer, and it seems that models equipped with 1/10 second direct reading CAL.3600 are becoming mainstream. *The role of the needle is slightly different from that of a typical chronograph. The 3 o'clock position in-dial has a chronosecond hand. It is an in-dial 60-minute counter at the 6 o'clock position and a permanent seconds hand on the 9 o'clock in-dial. The center hand is a chronosecond hand for 1/10 second direct reading. The center hand of a typical chronograph takes 60 seconds to complete one lap, but this model makes 1 lap in 10 seconds, so it moves at a fairly high speed. As can be said for chronographs in general, please turn off the stopwatch function except during measurement. In particular, I think this model will put a considerable strain on the mechanism of the chrono part if the chrono is running all the time. *The touch of the push button feels relatively good, and the 1/10 second chrono needle hardly pops when starting the chrono. When the needle is stopped, the Chrono 1/10 second hand recedes slightly and then stops. There may be differences in preferences for this movement. *The previous El Primero had a dial with a fine scale dividing 1 second into 10 equal parts, and was sometimes advertised as a chronograph capable of measuring 1/10 seconds, but it wasn't very practical. This model comes with a needle for direct reading of 1/10 seconds, but even with this method, I don't feel like I can read the time instantaneously. I don't think many people buy luxury watches for measurement purposes, but think of them as enjoying the fun of hand movement due to mechanical mechanisms. *The 1/10 second direct reading chrono used to have a CAL.4057 with a flyback, but production may now be discontinued. Does it mean that the CAL.3600 is the successor model? Note that the CAL.3600 does not come with a flyback.
