Restoration of a neglected citizen promaster japanese dive watch automatic NY0040 cal. 8200A
This time I did a full restoration of this brocken citizen promaster dive watch automatic. the movement was a miyota cal. 8200A equavalent to cal. 8205 ref. NY0040
This watch was severly damaged! the palletfork was not engaging with escape wheel. Glass and the bezel had many scratches and I had to change them both!
1977 Citizen launched his most successful series of 11 1/2 line mechanical movements, the 8200 calibre series. The maximum version with automatic winding, date and day of the week display was the Citizen 8203A calibre. It was later replaced by the practically identical Miyota 8205.
Even with the base board it becomes clear that this movement is designed for durability, every bearing, with the exception of the barrel, has a bearing block, cover stones do not exist except for the balance bearings.
The complete gear train, including the automatic movement and the lock, is mounted under a single large wheelhouse bridge. Only the minute tube got its own small bridge, because the indirectly driven central second drive goes through the minute tube as usual.
Half vibrations per hour: 21600
Number of stones: 21
Shock protection(s): Parashock 1 (Citizen)
