I am sure it has the correct specs, but wrong description. This happened to the Oris Carlos Coste, too.

Whoops, my bad. At least I didn't suggest Jack Daniels...

I love "The Glenrothes". Lagavulin 16yrs if he likes it smokey. But I'm far from an expert...

Dude... Check out my test! It's a man's watch.

Thanks for the ride!

Welcome back, Vic!

Thank you all for your nice words! It's nice to see this watch gets the attention it deserves here unlike on the other boards. Weird. There are at least 6 links that DO NOT work on my watch. I don't know if they are just really stuck or if they are from a different batch. Honestly, I did not notice the different coloured link, thanks for pointing it out. Also I have to say that an out of the box GST chrono would not have gotten this high rating. Good idea, maybe I should do that too.

The genuine Aquatimer is wr up to 120m... you can swim and snorkel with it. Sure. Showering is a different thing. The watch heats up very fast and maybe cools down as fast, too... Watches, constructed out of metal that reacts to temperature, are not meant for sauna, hot/cold showers or jacuzzies. No matter how wr they are.

Gotta disagree. I just did not hit the button because I don't like it. I think our reps are often better than we think they are. Hope I can proof this soon...

Sure it would. But it is hard to find a machine that can test up to 200m...

If you lay it on the radiator, or in the sun... Does the crystal get clouded from the inside?

Thanks Maximilian, I updated the test with your info, already. Really appreciated. Dude, I did not want in any way take guarantee for every single GST chrono rep out there... Even though the last watches I bought make it hard for me to believe there is NO QC at all. I mean how many watches are purchased on our boards in one month? How many members complain? I did not say EVERY rep of this kind will survive 50m - I just test the watch I have as is. This one had no problems, as well as 20 other reps I had pressure tested. Only one really failed, the watch I regard in my upcoming test...

I love Glash

Well, thats the money IWC charges for a deployant alone... Great combo!

I first fell in love with this watch after having seen Pugwash’s pictures of his Franken. The simplicity of the design, the way the white hands strike out of the black dial and of course an understatement that is representative for IWC made me want this watch really bad. (Picture courtesy of Pugwash) The GST line was introduced by IWC in 1997 to follow the Ocean-line after the end of the famous design-collaboration with Ferdinand A. Porsche. Together with Porsche, the IWC built watches like the Ocean 2000 for example, a diverwatch used by several military special forces, such as the German Kampfschwimmer (commando frog men). This one even has a military stock number: But IWC did not fail to create a worthy successor with the 3536 Aquatimer, head of the new sportsline GST. A very professional divertool water resistant up (or down) to 2 kilometers into the deep. The designers from Schaffhausen kept the puristic appearance of the Porsche-Design, holding close to the principles of the modern-classic. Marcel Breuer, one of the Bauhaus founders once described the Bauhaus credo: “At the moment we have built every part to function and not to disturbs the other, we’re done”. This functionalism even strikes through into the name GST, which simply stands for the used materials: Gold, steel, titanium. The slightly smaller brother of the GST Aquatimer is the GST Chronograph Automatic. Its design lead into the current Aquatimers, with a completely round body where only crown and pushers stick out. The lughorns seem to grow out of the case creating a one-piece-construction appearance. The GST chrono has also the typical inner bezel, which is not for diving, but a tachymeter scale. Often wrongly described as an Aquatimer, it is not. Only the look was obviously inspired by the Grandfather-Aquatimer, the very first IWC divingwatch. It is merely a sportschronograph, but with a waterresistance of 120m you can safely swim and snorkel with it. In my own biased opinion, the titanium versions of the GST line are the most beautiful. While the dials on the steel and gold pieces are white with blingy golden indexes, the titanium watches are equipped with a silk-matt finished black dial with bright white indexes and font. Also the steel cases have a polished finish which takes a lot of the sporty character. A statement that feels like “I want to wear a sportswatch, but actually I am too rich to use it". I apologize to all two-tone submariner fans out there. Genuine Technical Data: Reference: 370701 Caliber: ETA Valjoux 7750 Movement: Selfwinding mechanical Powerreserve: min. 42h Vibration: 28.800bph Jewel: 25 jewels Calendar: Day and Date Case: Titanium Grade 2 (5% Legierung) Water resistance: 120m Crown: Screw in Caseback: Screwed in Crystal: cambered sapphire Diameter: 39.7mm Thickness: 13.9mm Lugsize: 20mm Weight: 135grams The replica’s case has the same dimensions as the genuine item and is constructed out of three parts: bezel, body and caseback. The whole watch is made of titanium, including the bracelet system. Usually titanium is a material which is as strong as stainless steel, but 45% lighter and softer. Therefore you have to accept scratches very short after wearing. IWC solved this issue by having every ti case hardened by nitrogenium that is blasted against the surface with high pressure, compact it to grade 2 titanium (material grade number 3.7035), the same grade of titanium that is used for engineering high-tech machines and grounds. I have no idea what the replica manufacturers do to the rep material, but it does not scratch either. Compared to the old titane Avenger reps, the GST chrono is really scratch-resistant and feels way harder. Another advantage of titanium is that it’s very resistant against saltwater, but it ages by time. This means it gets darker. This happens to our reps as well as to the genuines. The 1,5mm thick caseback is of a screw-in type and sealed by a gasket that sits in the body. It has the correct markings “Inernational Watch Co. Schaffhausen” and a laser edged serial number. Inside the caseback you can find the IWC logo, the “INTERNATIONAL WATCH Co. SWISS TITANIUM” text and the same serial number as on the outside and the reference: 3707. The bezel is connected with the body very tight; there is no gap between the two parts. It is larger in diameter allowing the crystal to be almost the same size as the case-body. Like the slightly higher sitting crystal it is a little cambered. Even though this looks nice, there is a higher danger of breaking the crystal because it is not protected by the bezel. The entire case is what I call a real highlight in both, gen and rep watch history. It is build in a high grade of quality with little tolerances. I think this is a result of IWC’s long time experience in in-house case construction and the rep makers long time experience in copying it. Nothing is sharp or undefined, even the engraving on the caseback feels smooth. The crown sits on the tube like on a thrown. It is of a screw-lock type, but you won’t see a thread as it is hidden inside the tube. This is intentional. As always, it is not as defined as the genuine counterpart, but still better than on every out of the box rep submariner I have seen so far. It is marked with the fish symbol that vanished together with the GST line. It means the watch is water resistant. IWC guarantees a water resistance up to 12 bar (120m) on the genuine, my watchmaker’s Bergeon pressure-tester does the same for 50m on my rep. Maybe I will ask him to take it to a 100m+ tester along with the Oris I tested here. Remember that the pushers are not screw locked, so do not push them in the water. Neither on gen or rep. The movement behind the caseback is in this case an unfinished ETA Valjoux 7750 which means it is still in the same condition as it left the ETA production facilities in Grenchen, Switzerland. It runs now unserviced for more than 5 years, as the preowner bought it used, too and did not service it neither. Just a guess though. Therefore it runs like a charm and I will have it serviced as soon as my other projects allow spending a buck on it. Right now it shows an average accuracy of -44secs with an amplitude-difference of 73

WOW, thank you guys for all your kind words! I am already working hard on the next test, thats why I did not respond earlier. @Pix: my wrists are girlish, 16,5cm one time around.

I honestly hope not...

Looks gorgeous!

Awesome pictures as always. I wish I could take pictures like you! Another great post from you my friend. Thanks for all your work!

WOW, this is one hell of an AP collection. I really like the EOD, it is definately on my list.

I always admired the understated but sportive Oris diving watches and was very curious when rumours appeared that one would be repped in hiqh quality. So it was an easy step for me to jump the bandwagon after Silix introduced this 3 weeks ago. Now I will try to examine if the rep is as good as I had hoped… There aren’t a lot of companies building watches that are water-resistant more than 600m, and even less that build chronographs for these depths. By introducing a chronograph that can go down 1.000 meters, Oris proves that it plays in the premiere league of diving toolwatches, next to Breitling, Sinn, Charmex, Suunto and Girard-Perregaux. Of course, Charmex has pushed it really over the edge with its 50mm large and 12.000ft pressure-resistant Swiss Military watch, which is a chronograph as well. But with 3281ft the Oris Carlos Coste Chronograph will stand any atmosphere even professional divers might reach. Like you can guess from the name, the watch limited to 2000 pieces was developed in partnership with free-diving world record holder Carlos Coste.

100% genuine. Great taste, ryaku!
