“Citizen Chrono Master”, what a beautiful sound!
This is the Day-Date automatic version, ACSS 2929 Y GN2. It is made in a stainless steel case with a screw in caseback. On the caseback the eagle medallion gold inlay proudly proves the high grade of the watch. The case finish is superb, having clean lines, angles and polished surfaces.
The movement is the Citizen calibre automatic 5240 with 33 jewels, beating at 18,000 bph. It can be hand winded too. Chronomasters can also be a date only or even no date. There are some Chronomaster movements adjusted to a higher precision called Chronometer. This was possible by the adjuster positioned on the balance. It is a quick set date, and it hack for better time setting. The day changes by advancing the hour hand past midnight.
Some of these watches came on leather straps, others on stainless steel mesh bracelets. I have yet to find a real one on bracelet. The one presented here was made in 1968 and back then had a price list of 28,000 YEN.
