Mil-Spec (abbreviation for Military Specification) refers to the US Department of Defense military standard. Only when a product meets these highest standards of sourcing, manufacturing, materials, quality and delivery can it be called a MIL-SPEC inspired product or component. A real seal of quality. The Luminox 3350 Series watch is built to the MIL-PRF-46374G performance specification standard. This means that their water resistance, robustness and overall quality reflect US Department of Defense standards.

MIL-SPEC (ETA F06) movement data.

Typical rate Preci-Drive: (U=1,58 V) Initial rate with a normal wearing between 20-30°C.

•Initial rate: i.e when movement was delivered by ETA
•Normal wearing: no strong shocks, no sudden big changes in temperature
•At temperature of 20-30°C: other temperature can influence the accuracy.

Under these conditions, the movement will show an accuracy of +/- 10 seconds per year. This is under ideal conditions only, as set forth above.
