Seiko 6119-6020
The 6119-6020 is a Seiko 5 Sports from 1968 and 1969, with the 21-jewel 6119 automatic and a day-date at 3. The black dial reads SEIKO 5, SPORTS in blue, WATER 70 PROOF and 21 JEWELS over the Suwa mark, with the dial code JAPAN 6119-6020S at the bottom edge. Lumed baton markers sit inside a minute ring numbered every ten minutes, the seconds hand is red with a lollipop tip, and the crown sits at 4 on a cushion case of about 38mm. WATER 70 PROOF places the dial before Seiko changed the wording to WATER 70m RESIST around 1970. The 6119 neither hacks nor hand-winds. The submitter dates this example to July 1968 and fitted a period Maruman bracelet in place of the original.

How can I date a Seiko 5 Sports 6119-6020?
The dial and caseback wording is the first clue: early examples read WATER 70 PROOF, and around 1970 Seiko changed it to WATER 70m RESIST. For the exact month, read the caseback serial: the first digit is the last digit of the year and the second is the month, with O, N and D for October to December.
What are the movement specifications for the caliber 6119?
The Suwa-produced caliber 6119 is a 21-jewel automatic movement that beats at 21,600 bph. It features a day-date complication with a quickset date operated by pushing the crown in, but it does not hack and cannot be hand-wound.
