1977 – Digi Solar

Shown here is another watch without a brand name. The face has the inscription, “ Swiss Chronograph Digi Solar Swiss.” The back of the case in inscribed, “ Swiss made EE 35002S Use Mallory Battery 10SL 18 or equivalent.” This appears to be based on the same Brown Boven movement as the 1977 Mondaine Digi Solar. The date for the watch shown is estimated from the date known for the Mondaine Digi Solar.
