So I had a day off today and thought I would spit shine the Hamilton I bought the other day. You remember this guy here.....

1957 Hamilton Automatic Jan2010antiqueshow004

First I removed the band and tossed it in the used bracelet drawer, it's broken but you never know when you might need a part for an original bracelet. Then I polished the crystal (and the whole outside of watch) with some motorcycle windshield polish, the 10Kt gold filled bezel polished up fairly nice. Here what it looked like after about 20 mins of polishing:

Then it was time to pop the back off and see what we have inside. (This thing looks like a flying saucer from the side!!) Don't mind the green stuff at the gasket mating surface, she did her job for 50+ years and kept the inside clean. I cleaned all that off any way and put in a new gasket. Inside is a lightly decorated Hamilton 661 automatic, 17 jewels unadjusted, it has an odd toggle switch to remove rotor. Movement is based on a Kurth Freres 28.45, but I can't find much info on either movement.

All seemed OK inside, so this will be a nice one to send off for a full service. I slapped on a new band and will add to the collection. It feels good to wear one of these old watches, who knows the last time it saw any wrist time?

I did find some info on the movement after all, the KF was also used by Certina.....so once I put in Certina 28-45 I got this:

The 21 Jewel version of this, Hamilton had a 20 jewel version IIRC.....

That sucker turned out SUHWEET Gary! I see you are no stranger to tearing watches apart by the tools in the backround of your pics! Definately a keeper. What case size did they use in that model? 36mm?

Ok so here I show my lack of knowledge yet again. Why are some movements adjusted and some not? How much of a difference in +/- sec does adjusting the movement make in comparison? Are COSC certified movements the only ones adjusted? Does a bear crap in the woods? Is Poli BAND????

Good eye! It's 35mm, I know...teeny tiny in todays world, but some of us like the vintage look. I can always glue it to the top of an Invicta Russian Diver. I read they were going cheap in another post!!

Here is a great article on watch adjustments....

http://www.trusted-forwarder.org/elgin/technical/adjustments.html

and yes I think Poli is BAND!

Adjusted means that it was essentially timed in a variety of positions and/or temperatures. What that means is that we know a watch does not sit like clock in a single position in a temperature controlled environment. That means that the works are subjected to different effects of gravity, angular momentum, and temperature variations that can impact the accuracy of the movement. Adjusting across those factors can turn a watch that is fairly variable into one that is much more consistent in the time that it keeps in real use. More adjustments, in theory, means more likely to be accurate over the full range of uses and environments. In genuine practice, prior to about 1975 or so, 5 adjustments and Temperature were about the height of such in real watches available to the non-Millionaire.

Here is a 1950s Bulova that is adjusted in 5 positions, Isochronism, and Temperature. That makes it the top of the line in Bulova movements at that time.
1957 Hamilton Automatic Bulova55-23j6adj9

Can't recall where I found this but I've cut and pasted this list in from somewhere years ago.

The usual array of positions include a subset of the following positions:
1) Dial up
2) Dial down
3) Bow up
4) Bow down
5) Bow left
6) Bow right

These positional adjustments are intended to insure that the watch is just as realiable and accurate regardless of the position in which it is stored or used. In addition to positional adjustments, the watch may also be adjusted for Temperature. Temperature affects different elements in different ways. Heat will cause some metals to expand faster than others, and cold may cause some metals to contract more than others. A watch that is adjusted to temperatures will usually include some combination of metals that allow the watch to maintain its proper functionality within a larger range of temperatures than one that is not adjusted for temperature. Another type of adjustment is Isochronism. As a typical watch spring unwinds the pressure it exerts on the wheels of the movement reduces. This has the potential to create a difference in the operating speed of a fully wound watch versus the same watch in an nearly fully unwound state. Adjustments for isochronism attempt to compensate for this potential by maintaining the same pressure from the spring throughout most of the operating range of the watch. This sort of adjustment was generally seen only on the finest railroad grade watches of the 20th century.

The general rule of thumb with adjustments is that more is better. However, for average every day use, a typical unadjusted watch was perfectly adequate.

Holy Macaroni THAT'S good Gary !!!! 1957 Hamilton Automatic Icon_cheers The way you got
everything shined up, it must almost look like it did when it
was new ! The case and crystal look great now. Even the
movement is outstanding. Superb job on your Hamilton sir !

Outstanding Hammy! I love that broad beveled bezel. That's a tongue-twister!

BTW, I think I read that COSC wasn't created until around 1971.

Tom,

My recollection was mid-70s so I put around '75 but it may well have been '71. Prior to that watches with 5+ positions and TEMP and/or ISO were the best movements available as I understand it.

Nice job on cleaning that watch up Gary! Love the case design. As a matter of fact, I like most of your timepieces! Looks like you have some of the right kinds of tools to work on watches. I need to get some for myself.

Thanks, Dale. Now if I only knew more about it.
Don't want to steal thread. Maybe I'll start another some time.
The buckle still fits in the same hole, haven't really worn it since the late '70's.

Hey Robert! Actually, I missed where you earlier said 1975. Sorry. And I was just speaking off the top of my head when I said 1971. I just checked wikipedia: spilt the difference: it was 1973! 1957 Hamilton Automatic Icon_lol

lol! No problem. I was going by my poor memory too. COSC was a reaction to the quartz revolution is what we need to focus on here.

Some of our older watches (I say "our" in my sad attempt to place myself in a group with you Tom) from back-in-the-day that are Adj 5 + Temp are actually the top of the line for then. My Bulova that is 5+Temp+Iso was a rather expensive Chronometer grade equivalent for the day. Your Omega Connie must be one of the very earliest COSC watches.
