The photos presented below are of the actual item for sale. Kindly study them carefully because what you see is what you will get. We try our best to describe watches as accurately as we can that's why we present them visually & literally. In case we missed a few points, you are welcome to ask questions.

This "primitive"MORTIMA Super Datomatic Explorer features broad-arrow hands & a sturdy explorer case. Though primitive, its design is bold & daring - featuring a dual bezel (black ring rotates while silver ring is fixed) & a rotating tachymeter (reminiscent of the RADO Captain Cook).

EXTERNAL CONDITION: This watch is in *VERY GOOD condition (83-87%): The watch shows what might be considered normal wear by a careful owner who wore the watch regularly. Scratches are evident, but no nicks or dings. May have replacement parts. A sound, attractive presentation overall.
INTERNAL CONDITION: This watch is in *NEAR MINT condition (93-97%): working perfectly, keeping good time & needs nothing.
*condition descriptives mainly based on the Timezone Grading System

The MORTIMA watch label was owned by French company Cattin & Cie, which later migrated operations to Switzerland. MORTIMA was discontinued after the "quartz watch meltdown" in the early 1980s, but Cattin & Cie persists to create private label watches today. Their limited production makes these watches very rare & highly sought after!
