Bexei-Primus-Tourbillon watch by Aaron Becsei

Aaron Becsei was born in Budapest in 1979 and is the 3rd generation of a watchmaking dynasty. He grew up surrounded by watches. After secondary school he graduated from the Watchmakers program. In order to develop himself as a watchmaker and to get the necessary practical experience he started to work on watch repairs with his father. To have a deeper engineering knowledge he went to the School of Technical Sciences of Budapest in the faculty of CAD/CAM design. Aaron Becsei’s graduation thesis paper on his Tourbillon watch was honored by the Chamber of Engineering in Budapest. In 2003 he finished his first clock. This Miniature Double Pendule Zappler was fully his design and made by hand. After one and a half years of work his first Tourbillon clock was finished.

In 2005 with his Tourbillon No.1 clock Aaron Becsei was granted admission to the AHCI as a candidate and in 2007 he showcased these two clocks: the Tourbillon No1. and the Miniature Zappler at Baselworld 2007. His timepieces show respect to traditional watchmaking and are built with the most precise methodology. The Toubillon No1. table clock has a calendar, moon phase, wind up indicator, thermometer and a world time function. This clock has duplex tourbillion escapement and a unique engraved background making it unique and spectacular. His newest project is the design and development of a tourbillon wrist watch which has an extremely complicated and unique movement. Respecting traditional watchmaking he invented the three axis tourbillion movement without ball-bearings which is a unique solution at this size and level of complication. (Patent pending.) This wristwatch also has an incomparable engraved dial and had been presented in 2008 at Baselworld.

The first sketches of Primus were made on the 1st quarter of 2006. He knew that he wanted to build and triaxial tourbillion table clock with not using ball bearings at all. Also Aaaron wanted to create a unique wrist watch under his name. So he decided to make this two dreams happen in one timepiece.It was a crazy idea and almost no chance to implement this system at that size. He had all the plans about the system in his mind, so in 2006 he started to make the design and put together the plans to create this exceptional wristwatch.

Aaron spent almost half a year with the development only. He had to take into consideration the fact that this should be a size of a wrist watch and should work not on the papers only.The most challenging was to have this complex system operable at this miniature size. It took more than 1 year to get the system alive and it was a real present when the escapement started to work on 2007 Christmas Eve. After this all the parts had to be finished at the highest level and we are talking about these extremely small sizes you almost cannot imagine.Actually Aaron personally made all the parts from the case to the last screw. Except that the glass and the engraving were made by some of his friend-colleagues.

As you may know the tri axial solution is the best in order to avoid the bad effects of the gravity to the balance wheel. In a watch with a simple tourbillion system you leave the watch for 8-12 hours by night at the same position then when you wear it takes several different positions. That is why the adjustment is very problematic. With this triple axis system the balance wheel takes 3750 different positions in every 12,5 minutes day and night. His dream came true creating a unique Bexei timepiece; something what has a special and rare complication and is made with exceptional quality and craftsmanship. We think whit this engraved dial this Primus wristwatch will makes the owner feel like he owns/wears a piece of art.
