1930s or 40s New Haven

Recommended Posts

Just a couple of pics of a recent service.  Ran the movement in cleaning fluid for a week with a couple of fluid changes.  Lots of crud came off.  Polished the crystal and case, polished up a vintage band.  Oiled and running like a champ now.

Thank you for this treat, I seldom see movements like this one so for me it's super intresting.
Since i like movement porn I have one question, on the first Picture one can see a Little lid in the opposite corner of the balance; I assume this is were the mainspring is. From the Picture it seems the mainspring doesn't have an barrel? Is it just a mainspring and one arbour under the lid?

Yes, you remove the two screws, and the plate comes off exposing the main spring.  There is a main spring barrel there.  If I had a side shot you would see it.

Westclox and Timex are similar movement designs with only two plates.  This movement was quite easy to work with, especially how easy it was to remove the balance.

I have a very limited experience from movements like these compared to Swiss movements.Lately I have mostly worked on TIMEX watches since they are common here too.
One have to admit they are just ingenious in their simplicity, even they are made out of pressed sheet metal they mostly after a service starts ticking, not the most accurate but still considering the construction impressive.
I have begun to buy all kinds of pin lever escapements too. For some reason I get amused of the challenges they present. If one is interested in learning about the effects of side and end shake they are a joy to observe. In a fault finding perspective they mostly offer a greater challenge too.
Thank you for your response and keep up with the great work...

    • If the clock has a lack of oil say the platform, you will find it will not preform, as it should do no matter what you do. It is such a delicate and vital part it has to be in tiptop condition for it to work correctly, 
    • Caliber is generally engraved next to the ballance wheel.
    • You said it gains about a minute every 24 hours, I see the beat adjustment lever (the one that is bent downward over the back plate) is pushed to one side, this lever will advance or retract the beat therefore speeding the clock up or slowing it down. Also check to see if the balance spring is free in the slot of this lever if not it may be putting too much tension on the spring. Just so you know, the closer the slot end of the lever is to the end of the spring (where the taper pin holds it) the slower the clock will run.
    • It's very difficult to provide help without pictures. From the information you've provided, I can tell you that Omega pocket watch with movement number 5,694,216 would have been made between 1916 and 1923. The 15 jewels and 2 adjustments would align with these dates as well. I do not know what "Fortune" or the other number mean. Here is a picture of a watch made in the same time period...does your movement look like this?
    • Hi Andy,  The link introduces/defines Thermodynamic which is the study of heat energy conversion to work and vice versa. It is about transformation of energy. One form of energy (heat) transforming into another form ( work) and not concerned with transfer of heat, from hot to cold. Understanding the nature of heat and the mechanism heat transfers from hot source to cold, is a key len33 is prepared to use. His question shows him ready to absorb the concept. Regards joe
