Military NATO Chronograph 798-22

14.6 mm Cal. Lemania 5100 Self-winding Stainless steel

7 g in all directions, 200 metres below sea level, 15,000 metres above — this mechanical microcosm remains unaffected.

Heritage Collection

Bundeswehr-selected, 1984. NSN 6645-12-194-8642.

Produced: 1984-2008

After careful scrutiny of the offers, the German armed forces awarded the contract to Tutima.

Why It Matters

7 g in all directions, 200 metres below sea level, 15,000 metres above — this mechanical microcosm remains unaffected. The center 60-minute hand with its red tip eliminates the irritating, distracting search for the usual small 30-minute timer.

About This Watch

Dedicated edition for special forces – with crown and push-buttons on the left. This chronograph follows a timeless, function-first design. The robust stainless steel case with sapphire crystal and an extra-large case back protect the movement like an instrument watch built for demanding use. Clear 1–12 hour numerals support quick reading. Water resistance is rated to 20 bar. The chronograph features a large central 60-minute counter, a 12-hour counter and a 24-hour time display, powered by a self-winding movement with day and date. Dimensions: approx. 43.2 mm in diameter and approx. 14.6 mm in height.

Caliber

Lemania 5100

The Military Movement

When Lemania announced in 2002 they would stop making the Cal. 5100, Tutima had already stockpiled movements. Integrated pushers flush with the case — a military requirement for glove operation. NATO stock number 6645-12-194-8642.

Lemania 5100: 'We Took Precautions in Time'

· 2002–present

Lemania announced in 2002 they would stop producing the Cal. 5100. Tutima had already stockpiled movements. 'Wir haben beizeiten vorgesorgt' — we took precautions in time, said Dieter Delecate. The stockpiled movements serve two purposes — developing Tutima's own calibers, including the Cal. 521 with its patented central minute hand, and providing spare parts for servicing older military models no longer in production.

“People come in asking for Breitling or Omega. We introduce them to Tutima. The ones that are willing to do their homework and compare — normally coming back buying one.”
