The field style watch has been ongoing since WWI and continues to be universally accepted as a design that bridges the gap between rugged outdoors and suitable for dress. Luminox has upgraded the basic watch with the addition of A/R coated sapphire crystals, multi jewel Swiss quartz movements with 10 year lithium batteries, oversized crowns and the ultimate self powered illumination system found in all Luminox watches that glows continuously for more than 25 years.
