Changing colors frequently since 1974: Seiko Superior Morpho. A horological milestone in design but foremost in precision: the cal38 (Sampachi-Quartz) in its highest quality; exact to <=2s per month (!sic). Thats the result of using analog thermo-compensation -- something that "inspired" Rolex and was used in the OysterQuartz cal5135 since 1978.

Ad, 2025-11-20: Now, it is written here and there that the OysterQuartz cal5035 (resp cal5055) is using (analogue) TC -- but I have some doubts about this, now.
