Service Dials

Serial Number Range: N/A

General Notes: These are the tritium, luminova, and superluminova service-only dials for 1675’s. They’re fairly easy to distinguish and you can see them below. Keep in mind, however, these are not the only service dials. When watches were serviced in the 1960’s and 1970’s and needed a new dial, they were sometimes replaced with whatever dial was being produced at the time. Frequently you can see the Mark 5 and 6 dials as a service dial for earlier watches that were brought in during the later 70’s and early 80’s.

Distinguishing Characteristics:

• All the service dials have the same squat coronet and splayed crenelations.
• The lume plots are crisply delineated and there is not any smudging, like can be seen on the production dials.
• The luminova and superluminova service dials don’t use tritium so they don’t have patinated lume.
• The luminova dials have “Swiss T<25” at the bottom and the superluminova dials have “Swiss.”
