In order to illustrate the technical specifications I have imagined a little "interview" of the Lemania 5100 movement : here are its answers to our questions in italic orange !

First and Last name :

"You forgot to ask my rank !

Lemania 5100


Birth date :

"I start to get old ! but still active and sporty …"

1978


Size :

"Big and tall ! "

Movement height 8.2mm, diameter 31mm, weight 21g.


Type :

"simple and reliable"

Chronograph movement, self-winding with chronograph mechanism between the dial and base plate. Centrally mounted, unidirectional winding rotor.


Beats :

"Fast !"

28’800A/h


Characteristics :

"A REAL soldier !"

The central minute-counter, 24h indicator and 12-hour counter sub-dial. this unique feature in the chronograph world give to the Lemania 5100 an exceptional readability of the elapsed minute time

The movement of the officially issued NATO, German forces and Swiss airforces chronographs :

Tutima, Arctos and Orfina have been selected to supply the German Army , Airforces and Navy, with an officially issued chronograph , theses chronographs are all using Lemania 5100.

Here are the 3 officially issued by German forces chronographs all using the Lemania 5100


Design use :

"I Feel better in a MIG 29* cockpit than in a cocktail !"

The only chronograph movement who can withstand high shocks without the sweep secondhand stopping : the chronograph functions are powered directly.

Can withstand acceleration of up to 7 g, without the accuracy decreasing noticeably.

A legendary robustness with very few claims for services even in its military use.


Excellent accuracy, consistent over a long period between service : 5 to 8 years depending on use.

* As a reminder the MIG 29 is in service in the German airforce (they used to be in service in the former DDR), so the answer of our Lemania 5100 is perfectly correct in an aviation point of view ….

 


Construction

"Built as a Rock !"

The calibre’s bridges, plates and balance cock are built as a pillar construction.

The pillar construction is very unusual in modern wristwatches or chronographs : it is a technology generally used in old mechanical wristwatches or a mechanical alarm clocks.

The Pillar construction means that the cock and bridges are attached to the main plate by thin pillars.

In modern designs, the cock and bridges are terrace-like and mounted directly onto the main plate.

The big advantage of the Pillar construction is manufacturing cost because parts can be stamped , where the modern designs need milled plates

The chronograph mechanism navette-type, the calibre has a large Glucydur balance. Nivarox 1 flat hairspring, Triovis regulator, Kif-Flector shock absorber (comparable system to "incabloc" but not with the same design).

Many nylon pieces can be found in the caliber such as : day and date wheels, automatic winding mechanism reduction gear and the two "half moons" that support the rotor (see detailled pics of the movement at the end of this page)

COSC rating

"Yes I can be VERY precise even with my warrior look "

Sinn offers the 5100 (for an additional fee) with a COSC certificate.



Pictures of the movement

"I know you wanted to see bare pics ! you damned perverted collectors ! "

Theses pictures have been found on the excellent "Watchscape" site where you can find hundreds of movement pictures

Any conclusions ?

"I am not a fashion victim, I am a TOOL like a Land Rover Defender for the car analogy . Not designed to be nice but designed to do its task with the best robustness and efficiency"

We can hope that this unique design will remain in production for a certain time , unfortunatly persistent rumors are heard that the Lemania 5100 might go to retirement , hopefully a gouvernement contract links Tutima and German air forces to supply chronographs with the Lemania 5100 movement , but at the end of this contract it might be possible that the Lemania 5100 will definitely disappear from new watches

let the Lemania 5100 make a conclusion to this interview :

My duty is done ! OVER !
