He, that is nice

Here are my Amphibias:

Great stuff Tom, 960 and 350!

By the way you probably know why the 350 has swivelled lugs

Feel free to learn me something

Ahhh...

When Vostok was working on the Amphibia project they had not worked with stainless steel before, only brass. Brass is a really nice material to machine, with the right kind of cutting tool it takes only one pass to shape it. Stainless steel on the other hand, is much trickier, while being hard it is more brittle as well. The earlier tests on machining stainless steel ended up with the lugs falling off, so they resorted to having lugs added to the case. Later on, they discovered that they could indeed machine watchcases with regular lugs, but they had to cut in multiple passes: basically, cutting off smaller amounts of material every pass. Compared to brass which needs one pass of the cutting tool, stainless steel needs twelve.

When I was doing metal machining (both lathe and milling machine) many years ago I did try different materials; brass and steel are nice to work on, aluminium is very "sticky" and clogs up the cutting tools quickly, but working titanium is a little less fun than hitting my own head with a hammer repeatedly!

I´ll try as well:

this is the new stuff...now older:

and two of my first ones:


after all the famous radioroom:

the KGB by Ostwok and a W&CM amfibia


and again some new stuff: new ministry and reef diver


Thats it folks...

Anyone have two-crown Amphibians?

Anyone have two-crown Amphibians?

...such has never been made by wostok...mybe poljot did, but most of us (?) do understand amfibia as wostok made watches.

Yes, now I remember. One of our members of the Dutch Watch Forum posted this article from a Russian forum in 2009:

It is a nice article about the development of the Amphibia watches.
I tried to read it with Google Translation . Great fun!
Maybe somebody is willing to translate it in good English.

Check out this article, at the bottom you will see a two crown Amphibia, made by Boctok:
