In 2003 Doxa released the SUB 250 Sharkhunter. It is a reissue of the original SUB 250T. The T which signifies Tritium was dropped because during production Doxa were informed that US and EC regulations will not allow importing watches with Tritium coating in the near future, so they switched to Super Luminova. However, there were a few of the early watches from the production run which did use Tritium. The domed crystal of the SUB 250 Sharkhunter is made of hesalite. Interestingly enough, this is the same material the 1960's phone sets were made of.
The SUB 250 Sharkhunter uses the ETA 2452 movement. This was the Caliber used in the original DOXA SUB 250T from 1973 till 1995. The reissue SUB 250 Sharkhunters are basically New Old Stock (NOS) watches. The movements were stored for more than 10 years as Ebauches (the French term for movement parts) in their original DOXA sealed packages, the cases too. The movements are assembled, lubricated and run in then assembled in their cases individually, by hand.
The design of the SUB 250 is closer in design to the original SUB 300T and ships with a leather strap. However, as the lug width is a standard 20mm, there are numerous aftermarket braclets which will fit.
I don't have many photos of the SUB 250 yet. Thanks to Andrew McKinney, Henry Chen, Simbo and NYRenaisanceman for these and Doxa for the picture of the original SUB 250T.
