The caliber could definitively tell you the manufacture date. Without "hack" feature and in the 8888 case with that dial, you may have a cal 32A, one of the 662 manufactured in 1967. Ive attached a pic of my 8888 with 32A. I also have an 888 with 42.1 (also 36000A/h) but this has a different dial from 1970-74. My watchmaker sets the movement to +2sec/day when he services the movement expecting that it will slow over the next 10 years rather than needing service after 5 years.

For the record
when I tried to "hack" the seconds hand while setting time initially, the watch was running consistently +15 seconds per day for 2 -3 days Just for the fun of it, I put it down, and let the power run down then I adjusted time without worrying about the se...
