Hi Andy, The AT-VC (3231) front crystal is 2.20mm thick. From lower edge to the top of the dome it is 3.50mm in height. The GST-AT (3536) crystal is 3.70mm thick. Leo

Great topic! Any info maybe about the crystal of the youngest Aquatimer Chrono ref. 3767? I semm to remember a back issue of the Watch International where the Fliegerchrono 3706 was mentioned to have a crystal 0.8 mm thickness and this was mentioned as thick... I'm not sure to remember correctly though. As I have this issue somewhere I can look after this info when I'll be back from holidays (on my wrist my Cousteau chrono 376706...) Best, Robert

Leo,
Thank you so much for taking the time to verify the "crystal thickness" of the VC-AT.
I'm curious...is there some reference you use that is available to Forumers for future inquiries?

Hi Andy, I have been the head watchmaker/manager of the IWC-UK workshops since 1999 but the precision, rather than experience, required in response to your 'thickness' question had me referring to our internal intranet database. I thought someone might pick me up on it, knowing, as a fellow forumer, the thirst for more IWC knowledge held by forum members. Although not quite'Top Secret', it obviously can't be accessed by, or published for, the general public (or unfortunately Forumers). That said, I am more than happy to offer replies (within reason) that require access to the database through the normal forum. Leo

Leo,
I can only imagine the wealth of information you have acquired as a watchmaker along with your capacity for IWC. I fully understand the restricted access of the companies proprietary database and appreciate your invitation to help answer (reasonable) questions from fellow Forumers.
Over the last 18 months, the "virus" has done a number on me and my wallet. My appetite for learning specific details about each new model added to the collection has been one of the "side effects" of the infection. However, I must admit, wearing IWC watches is just part of the enjoyment. Understanding the history, specifications and method of construction adds to the overall satisfaction of owning the IWC luxury experience.
Thank you Leo for offering your expertise to the Forum. The contributions from the many "seasoned" members make this site the go-to for the most accurate, up to date and reliable information about IWC.

@ Leo, I guess you know that us fellow forumers really do appreciate your inputs and responces. Knowledge held by Watchmakers like yourself and Jack are of great importance to ensure our questions are answered - and we really are thankful for that.

Hi Leo,
just reading again my Watch International back issues, in the 1/96 issue I've found a data the Fliegerchronograph having 1.8 mm thick crystal. This does not mean necessarily that one of the two data is wrong, maybe IWC thinned down the thickness as the watch has to withstand only 6 atm pressure. The 1.8 mm data comes from the earliest days of the Fliegerchrono production, that was introduced in 1994. I've posted this only as an interesting addition.

Hi Leo, When crystals are replaced for the Aquatimer during a complete service, do they get oven baked when the epoxy is reapplied for the new crystal? Would it be possible for you to elucidate the process of crystal replacement, particularly for the AT range?
Furthermore, does each professional Aquatimer (2000m rated) go through pressure tests again to the specified rating (i.e. 2000m) as part of the complete service?
Doing some research in the archives and found 1/2 the answer to my question from a post by Cellar (Sept. 5, 2007).
Does anyone know the crystal thickness of the VC-AT vs. the AT2000's(4.3mm)?
Thanks for any assistance,
Andy
