In this new series, black and white dials were manufactured in similar numbers for a closer to 50/50 split. In prior releases the lighter colored dials accounted for about 75% of the total production, with the black dials making up the other 25%. Lume was again updated, now at each hour marker as an integrated part of the indices. The silver linen dial was likewise replaced with an off-white dial.

With this version they replaced the black sunburst dial with a black linen texture dial. The hour and minute hands are carried forward from the previous model.ДЄt the end of 1969 SEIKO started production of the new 09 models. The GMT hand is replaced with a red version on both dial colors, with a new lumed arrow tip. In all previous versions these numbers were centered. The numbers on the top half of the 24-hour ring are left justified, while the numbers on the bottom half are right justified. On the 24-hour ring, the numbering changes from 1 - 24 to 0 - 23. No more mention of the jewel count or diashock feature. WORLD TIME is moved to the 6-o'clock position, along with the Suwa logo. This time the lumed dots at each hour marker are replaced with lumed indices at 12, 6 and 9 o'clock.ДЄ rectangular lume application is also placed at 3-o'clock, next to the date window.ДЄUTOMATIC is moved to the 12-o'clock position, under the SEIKO logo. The dials were again updated for the 1968 production of the 19. It is unclear if these are examples of the same dial, with some having faded over time, or in fact different color options. One has a more copper/gold or yellow tone on the bottom half, the other a more reddish bronze tone.

NOTE: There appear two be two variations of the black dial's 24-hour ring.
