Challenger – Black Luna

Challenger – Black Luna strong limited calendar chrono


Torsten Nagengast Timepieces (TNT) announced to produce a very special, limited edition of the latest Challenger model: The LUNA.

TNT requested FORaSEC to team up again and handle the sales and customer service for this project (like we do for the Watchuseek Rattrapante edition of the Challenger). We are pleased to say that production of samples has already been started. Realistically we could have the watches ready before the end of March 2014. Demand will decide if we will pull the trigger on production.

We decided to keep the price at a very decent € 1.198,- (€ 1.450,- incl. EU V.A.T.), as we believe our direct sales structure should benefit the customer as much as possible. A price level unheard of for this type of quality Valjoux-based complication.

That is why we ask you to let us know by return if you are interested in purchasing this watch via this link:

We will gather your info and if demand is sufficient, we will ask you to commit and pay a first deposit of € 500,-.
During the manufacturing process we will update you regularly on progress and show pictures or drawings when we can.
The pictures are computer renderings. 

The watch
The Triple calendar and the moon phase complication are custom made and have never been produced by Valjoux or ETA themselves in this combination. The Moon will be filled with STRONG Luminova for maximum visibility.
Fixed lugs and the coin-edge case body give the watch a nice vintage feeling. The unique movement enables an incredible number of functions: Day and month display, date, chronograph function and a fantastic LUMINOVA MOON PHASE!
We will limit the LUNA to only 85 pieces worldwide. Still, we will give the choice of three different dial colors to suit everybody’s taste: black, blueberry or silver.
€ 1.198,- excluding V.A.T. (outside European Union)
€ 1.450,- including V.A.T. (European Union)
Shipment: € 15 within the European Union (Incl. V.A.T.), €25 for the rest of the world.
First deposit (order intake) is € 500,- excluding V.A.T. / € 605,- including V.A.T.
Second and final payment will be just before delivery in February or March 2014 (to be confirmed) and will be the balance including any optional accessories chosen (strap, alternative dial color) and shipment.
