hi am  new to the forum 

i have recently stripped cleaned and serviced my first pocket watch ,a ingersoll pin pallet .i am looking for some information on its beat rate and what sort of accuracy i could expect as it seems to have a big difference in rate depending on which way it is up .many thanks for any replies

Welcome to the Forum, Pp. If your watch is as I think it is, beat rate and accuracy were probably not too high on the agenda at Ingersoll when these watches were being mass produced. An Ingersoll pocket watch was the first proper watch I ever had and I bought it new in the mid-1960s. Many of these inexpensive Ingersolls are are still going strong and I think you had the right idea when you did your first clean and service on one of these watches. My own watch was very like the example here below (pics from assets.catawiki.nl):

Thank you for your reply.

Yes the picture is the same type of watch ,I have about 8  of these with various faces plus some spares .I also have several other pocket watches some working others in need of repair .I'm hoping over the next few years to learn more on  how to restore clocks and pocket watches

did the ingersol run before you cleaned it?   the "up and down"  beat difference  usually means a balance staff problem.   check that again.   good luck , cheers,      vin

Hi guys,

This watches are a little bit different. They have balance bearings rather like in alarm clocks. Staff ends with sharp cones, not with cylindrical pivots. The cones lie in steel female cone cup bearings. This system is easy to produce, absolutely shock proof, and works very good. But, after 2-3-4 years of work, the top of cones will wear and friction forces will rice so much that the amplitude will decrease dramatically and watch will not work correctly and finally will stop…

This kind of watches are not intended to be serviced, but rather to be thrown away when begin not to work properly, and replaced with new watches… The price of the watch was comparable with price of servicing of normal  watch. Anyway, repair is possible, but one must learn how to sharpen the tips of the balance staff. The cup bearings wear too, but much more slowly than the staff. One will usually sharpen the staff 3-4 times before change or repair of the bearings is needed.

the balance staff of a cheap watch can be cleaned up.   BUT  what about the hole it slips into?  if you don't clean that up,   the balance staff will drag?   a cone shaped reamer might work.   vin
