Editor's Notes

Perhaps the most sleek of the minimalist designs in NOMOS Glashütte's 'Neomatik 39' repertory is this watch suited for daily wear and formal attires. It's engineered with the house's innovative automatic DUW 3001 calibre. A neon-orange second hand and white Arabic numerals pop against the black lacquered dial. Prominent and angular on the wrist and 46mm in diagonal diameter, it's set on a brown Horween leather strap that's been handmade in Germany.

We offer a two-year warranty for all working parts and manufacturing faults for luxury watches. For more information, contact one of our experts by emailing
