Regulation Question
Hi
I'm not interested in anyone flaming or trolling. This is a fairly simple question with perhaps a more complicated answer. I have a watch that several months old. This watch loses about .7 or .8 s/d. Yes, I know that is well within SOSC spec. Less than one second . MY QUESTION IS, WITH the 3135 movements, is there a way to Simply add one second? When they screw the four screws to tighten or loosen, can they do so where only one second is changed? Yes or no? Im kindly asking in advance that you Please not make up any other questions or Give opinions on how crazy I am. Thanks. |

There's no "quick simple way" to make watch run exactly 1s faster, there's no digital electronic governor that you can just punch in the required adjustment and the system simply obeys. It's a mechanical analogue device that obeys the laws of physics alone. Rotational momentum of balance wheel vs elastic properties of the hairspring. Reduce effective momentum by pulling weights closer to axle makes it oscillate higher frequency, experienced watchmaker would be able to roughly judge how much to adjust by at first shot, but nobody would know for sure until it's tested running again. |

Have a look here if you want to know how the tool used for adjusting the screws work:

Quite honestly there's no way I would mess with a mechanical watch that's keeping time to UNDER one second a day. These are mechanical devices that are affected by all sorts of things like state of wind, temperature, position, the habits of the wearer and so on. Under one second a day is not only fine, it's great. I'd also be surprised if it is currently keeping exactly the same time in different positions. You didn't say if your figure comes from putting it on a timing machine or if you're comparing it daily to a "good" time source or some other method. If you need a watch more accurate than that then perhaps you ought to look into some of the modern "high accuracy" quartz watches. There are some very nice ones out there. I wouldn't worry about under one second a day and will say that if you do you might be tilting at windmills in your quest for better timekeeping.

It's a mechanical watch so surely being a few seconds out per day is more than acceptable. If I want near absolute accuracy I will go radio-controlled.
