Service Dial, Tritium (Mark VI)
Explorer II Freccione 1655 — Service Dial, Tritium (Mark VI)
Replacement dial supplied by Rolex service, with tritium lume. Collectors sometimes number it Mark VI. Its “R” lacks the slight curve at the foot seen on the Mark V.
Five production dial Marks plus two service dials (tritium and Luminova), four types and two seconds hands. Sold slowly; a 1983 example sat at its retailer for six years. Dated case numbers run from about 2.7M (1971) to about 8.27M (c. 1984).
