When you have stainless steel screws, what do you need blued screws for? Bluing served a functional purpose at one time of preventing rust. It is now mainly decorative. You don't need to blue your screws if they are made of stainless.

 

looks like the finishing may vary a bit, this one doesn't look hand finished at all:

I'd rather see nicely polished screw heads than blued ones. The beveling is evident from 9 o'clock to a little past 12 o'clock, where the rotor isn't obscuring the bridge.

I think what they mean by beveling in this case is "anglage" from the French "angler" and I suspect that "Anglage" is Franclish. "angler " means either bevel of more correctly "chamfer". I don't think for the main part we can see most of it because is is hand done with chamfering tools. The technical definition of "chamfer" is "to form a small flat surface by cutting down a sharp edge" according to Berner's "Dcitionnaire professionnel de l'horlopgerie".

It saw anglage done at the Rochat plant in Les Buis . It was explaned to me that in truth, it is totally useless as far as increasing the mechanical quality of the watch goes, but it is a cosmetic surface treatment that makes the watch movement move beautiful.

It is time consuming and difficult to do and can only be done by hand using burnishing tools. I think this is what they are driving at by talking about "bevels" not what you and I would ordinarily mean by bevels.

 

Thanks for the thoughts everyone! That's a great point about the polished screw heads - I imagine nicely polished screw heads are actually more challenging to produce and arguably more beautiful than blued ones.

@Samantha - definitely can see the beveling on that photo now, makes sense! But is it strange that in another photo, the bridge seems cut with no beveling? Perhaps I'm overthinking this...

A blued screw is a polished screw then heated, so bluing is the more labour intensive process.

Personally aesthetically I only get blued screws on gilded plates, doesn't work on rhodiumed plates for me.

 

Agree that most blued screws are decorative...and not to be contrarian here...but might there be a benefit to bluing lower grades of stainless? Seems that heat bluing also adds surface hardening. Again...probably decorative...but just a thought.

 

I know this is an old thread, but couldn’t resist as I own a Sixties model (GO moved these out of the Senator collection and paired then with the 70s series for “Vintage”) with the Caliber 39-52. The movement finishing is beautiful, quite a bit nicer than the more mainstream brands at this price point like Tag, Breitling and Omega (which comes very close in some movements).

Where the GO Sixties models really excel however is in the dial. Mine is the simple time-only model with the white dial and rose gold hands and indices, but despite what should be a very simple color, the dial really has a lot going on. The hour markers at 3, 6, 9 and 12 Are beautifully painted in an eclectic font that resembles not only the original GUB watch on which it is based, but also some 1960s Times Marlins (this is a good thing). All other hour markers are incised into the dial and the grooves are plated in 18kt rose gold, as are the hands. The dial is also slightly domed with a pie-pan shape that I just can’t stop staring at.

Some complain that the movement is too small for the case and I can see where they get that from, but to me it is just a beautifully finished movement at the very lowest rung of high-horology, fitted in a watch that is entirely deserving of that classification, if just barely. Rolex, JLC, Seiko, Omega and even ETA have some movements with more advanced engineering than the GO 39, but none at a similar price point that are as nicely finished.

Just my $0.02 as a Sixties owner.

PS, I was attracted to this model by similarities with the 1956 Omega Constellation that I inherited from my father. I mostly wear that one on special occasions now, but the GO is my everyday office watch.
