While many of you have purchased your watch directly from us at DOXA ONLINE or through a Retail Partner - DOXA ONSITE; some of you have obtained your DOXA through a private seller. We want to ensure that you understand the warranty policy and how it impacts service for your DOXA watch.

The DOXA Warranty is a two (2) year limited warranty. The DOXA Warranty applies to the original owner/purchaser of the watch. When you purchase your DOXA watch, you will receive a warranty card that will list the watch serial number, and the date of purchase.

Only the person listed as the purchaser/owner of the watch will be able to receive DOXA authorized warranty service. IMPORTANT - you must have a completely filled-in warranty card to have a valid warranty.

Effective November 1st, 2008 DOXA Warranties will no longer be transferable to future owners of a previously purchased/owned DOXA SUB. The warranty will only be valid for the original purchaser/owner - i.e. the individual named as the owner with the service center.

Q. What movement(s) are used in DOXA SUB 600T?

A. The re-issues uses the workhorse ETA 2824 movement, decorated and refined by DOXA. The details of the mechanism can be found on the movement page.


Q. What is the relationship between DOXA and Jenny (pronounced Yanni) watches? Why does the fish logo for both look related?

A. Ever heard about the famous Jenny Caribbean diver's watch from the seventies, water resistant to 1000m (The first 1000 meter water resistant and patented wristwatch ever mad, incorporating the monocoque design)? - The logo shows a fish but implements the 'J' from the name Jenny as well. Now what has that to do with the DOXA SUB 300T re-issue ? - The Jenny Family are also Trademark Holder of DOXA S.A. - Mr. Jenny is DOXA S.A's CEO. JENNY (pronounced YANNI), it was his grand father who contributed with his know how to build the DOXA first SUB diver watch and he also manufactured watches for names like AQUADIVE, FORTIS, PHILIP WATCHES, EISENHARDT, JACQUES DROZ, and others. The case was revolutionary in that the case was made out of 1 piece so the movement was removed from the front.


Q. What is the relationship between DOXA and Synchron? Why do some vintage models say Synchron on the back?

A. After the crisis of the Swiss watch industry in the seventies, DOXA joined a group of Swiss companies to be able to resist the crisis the group was called SYNCHRON - it was in that time when the watches manufactured carried the logo DOXA by SYNCHRON. The following companies were part of the Synchron Group (Girard Perregaux, Eberhard &Co., DOXA, Borel, Cyma etc..)


Q. What is the relationship between DOXA and US Divers? Why do some vintage models have a US Divers logo?

A. The US Divers Co. was the official distributor of the DOXA SUB diver watch in the USA in the seventies. Also the Non -decompression dive table incorporated into the DOXA SUB models was developed in co-operation with the US divers Co. Jacques Cousteau was Chairman of the Board of US Divers from 1957 until his death in 1996.


Q. How do I use the no-decompression dive bezel?

A. The information on how to use the bezel is at: Bezel Instructions.


Q. Is the bezel calibrated in Feet or Meters?

A. The bezel of the re-issue SUB 300T has graduations in Meters. There are 2 major diving institutes in the world - SSI and PADI, and their courses adhere to the metric system. This was the reason for DOXA to choose the metric bezels but following the release of the 300T re-issue we received lots of inquiries regarding a SUB 300T bezel with Feet graduations, they decided that the new SUB bezels will be available in Feet, as they were on the original watch.


Q. Why do some of the older models not have a T in the name? e.g. SUB 300 instead of SUB 300T?

A. The T stands for TRITIUM which is the luminous coating on the hands and dial markers. It is radioactive. The "activity" used in watch making is limited to a value of 25 mCi (milliCurie) which means that no radiation will pass through the glass and / or the case of the watch. Many old watches had < 25 MC on the dial which means that the activity of the luminescent material used on the dial is below the legal limit of 25 mCi. The watches produced with another compound did not have the T. Recently Doxa were informed that US and EC regulations will not allow importing watches with Tritium coating in the near future, so they are switching to Super Luminova.


Q. What is the relationship between Doxa, Clive Cussler and Dirk Pitt?

A. See the Doxa website at: DOXA's visit to Dr. Cussler.

Q. Where can I find reviews of Doxa watches?

A. please visit or as well as the reviews on this site.


Q. What is the difference between a self-winding (automatic) and a hand-winding movement?

A. The difference between these two movements is the way in which the watch is wound. Manual-winding watches must be wound by hand every day, whereas self-winding watches are wound by an internal rotor. The internal rotor responds to wrist movements. Self-winding watches usually have a power reserve of at least 40 hours and therefore have sufficient energy reserves to maintain a stable rate when the watch is not being worn (e.g. overnight).


Q. Are DOXA watches shock-resistant ?

A. Yes. DOXA watches are shock-resistant to 5000 g


Q. Are DOXA watches resistant to magnetic fields?

A. Yes. DOXA watches are anti-magnetic in accordance with the definitions of the ISO 764 standard. This standard is based on the accidental passage of a watch in a magnetic field of 4,800A/m, i.e. 0.006 Tesla. the effect of the residual magnetism should not exceed 30 seconds per day for a gents watch and 45 seconds per day for a ladies watch.


Q. Where can I find wallpapers for the SUB 300T?

A. DOXA has several Windows wallpapers for the SUB 300T. They can be downloaded below in Resources / Info tab.


Q. What are the service intervals on DOXA watches?

A. Like any high-precision instrument, a watch needs to be services regularly in order for it to work perfectly. Obviously, we cannot indicate the intervals for such work, given that it depends entirely on the model, climate and the care taken by the watch's owner. As a general rule, it is between 3 and 5 years, depending on the use of the watch.

    J.E., Rancho Mirage, CA, DOXA SUB5000T Caribbean

    Just a short note to say that my Sub 5000T (68/5000) arrived in tact. It is an amazing watch and I could not be more satisfied. Special pricing made it possible sooner than I thought, and I believe I got a true bargain in a dive watch recognized around the world. My sincere thanks to all at Doxa who had a hand in producing my Seaconqueror.

    Dean, Alberta, Canada, 2006 SUB750T Clive Cussler Professional Edition 4504/5000

    Thank you for a brilliant time piece. The watch looks a million times better in person than in the spectacular photos on the official forum and on the website (which are what sold me in the first place). This watch is unquestionably one of the finest watches I have ever purchased.

    I am very, very glad I bought this watch. Doxa's quick turnaround and prompt responses to all of my queries was also much appreciated. I normally hate waiting for things, but like a very few select other parts of my life this watch was well worth the 4 day wait.
