I bought this 18s Elgin BW Raymond for a carry watch. It was a mess,but I polished the case,cleaned the dial,and dismantled and cleaned and oiled the movement. It now looks great and runs great,but was loosing about 2 minutes in 24 hours. I have advanced the regulator all the way,a bit at a time,till it is all the way over,and now it is down to about one minute a day loss. I checked the balance wheel carefully,and there are no timing washers,or timing screws on it. How can I speed it up a little?

If we assume that the watch was once good and kept good time, and that it has not been messed with around the balance area, look first at seeing why it is now running fast, check out on a timing machine see how it is really running, amplitude, beat etc and in positions this will be your first indication on the way ahead. Is it knocking, maybe a incorrect mainspring etc, once you are happy that everything is in order examine the balance and hairspring, from then on if all correct you need to see why it needs weight removing after all these years it is a tiny amount that will make the difference a spot of corrosion, some residue stuck to it etc, of course there are many other things that can cause this but just a few thoughts to consider.
Hey Chris, Thanks,I don't have a timing machine. The balance action looks good,hairspring looks to be original,can't see any wobble or knocking,the mainspring looks like a recent replacement,and I thought about putting in a new one to be sure it is correct. I will try that first,then I guess I can weigh a couple of the balance screws,and replace them with lighter ones. I wouldn't spend a lot of time messing with this,except I like the looks of this watch,and would like to get it right.

HI CECIL, I HAD A WATCH THAT RUN 5 MINUTES FAST A DAY , SO I TOOK IT TO MY WATCHMAKER AND HE MOVED THE 2 PINS ON THE REGULATOR , IT TOOK HIM 15 SECONDS AND THE WATCH RUN FINE. I DONT KNOW WHICH WAY HE DID IT BUT, IM SURE OUR WATCHMAKERS KNOW THE ROUTINE. I DO KNOW THAT IF THE 2 PINS ARE CLOSE TOGETHER THE RUN FASTER. IT SHORTENS THE TOTAL MOVEMENT OF THE HAIRSPRING. I HOPE SOMEBODY JUMPS IN HERE IF I AM GIVING MISLEADING INFO. LEONARD

Hey Leonard, Thanks,but I have checked the regulator pins,and they have the proper amount of "breathing" room. I have been too busy to get back to the problem,but in the meantime,I moved the regulator a little past the end stop,and it now is keeping time within about 30 seconds a week. I'm not working today,so maybe I'll get into it a little later today. The hairspring is pinned,so maybe I will try to shorten it up a bit. The watch is of little actual value,but for some reason I just like it.
