Here's another one ...


SJX thanks for the nice pics.
I am a big fan of Seiko watches. I have noticed this piece for some time but I still think that the "GSGSGS" dial is overly done and is enpowering the whole watch.
It is also very ironic that the normally low profile, almost-unadvertised GS would make so big a statement on the dial.
Any idea how the GSGSGS "guilloche" dial is done? Precision machining such as CNC or stamping? An insight into this proces might make me appreciate this watch more.

Thanks Steve and SJX. I guess the blue hands tempered? Or plated?
Steve your Credor photo is so awesome. They even put a blue cap over the shaft.
If I may reproduce your photo here...

Seiko uses "hot" bluing for its hands, i.e. the hands are blued over heat. By chemical bluing I was referring to "cold" bluing where a solution is applied to the steel without the for heat. From what I recall, cold bluing results in steel that looks the same but does not have the same degree of rust or wear resistance as hot bluing.

Heat bluing is a chemical reaction, and different temperatures and different periods over the flame result in different colours, but my knowledge of heat treatment ends there. Then of course there are some makers (especially producers of fake watches in China), that paint the hands a bright blue. :-)
As for rust resistance I have no idea. Gun makers say that bluing of the steel parts on firearms does indeed increase rust resistance so I assume the same holds true for watches?

I forgot about it while taking photos but it is visible to the naked eye. Unlike the surrounding GS logos, the lion logo appears flat. I have no idea what its significance is though.

...here's another shot of blued hands. I tried to capture some dramatic neo-noir lighting as well.

i didnt realise until it arrived how blue the hands are as they look black in all the pics i've seen.
this is the 'forgotten re edition', we get loads of posts on the Polaris, the Longines legend diver etc etc, but very few on this, the Seagull PLAAF 1963 re edition. a watch with long long history. originally a Venus 175 calibre, upgraded by Seagull from 17 to 19 jewels and recently from 19 to 21 jewels although it keeps its ST19 name. this movement has been consistently in use since the 1940's to the present day in several different case and brand variations and has proved to be utterly reliable. there are stories of poor quality control in some of the seagulls, but the majority are fine.


just a small offering
