I recently purchased a second hand Jaeger LeCoultre master geographic 142.840.922B (in perfect condition) - however the self winding mechanism makes a lot of noise - is this normal? any assistance helping me understand the idiosyncracies of this watch would be appreciated many thanks | ||

The rotor should make two noises: a very smooth and consistent whirring sound when the rotor is being spun and a very slight rattling sound then the watch is moved perpendicular to the rotor swing. The first is the sound of the ball-bearings as the rotor spins and the second is the sound of the rotor jiggling against the bearings as it shakes. Neither noise is very loud and you certianly shouldn't notice them unless the room is quiet and you are listening. What noises are you hearing exactly, and when? | ||

hi, i'm new to this forum--i'm considering purchasing a master compressor geographic. a seller is offering to meet in person and sell me one for about $ 4300. i haven't seen it yet, i was wondering what i should look for as far as quality and, if there are counterfeits, what i should look for. thanks. | ||

Hi, I recently purchased a new Master Geographic SS and have twice returned it to the seller for accuracy checks/repairs. What are the normal parameters for accuracy? In other words, I'm wondering if the watch loses more seconds for each 24 hr period if the reserve is at, say, 30 hours (rather than, say, when fully wound at 38-40). As it is, I'm finding the watch losing about 5 seconds for each 24 hour period; I should mention, 12 of the 24 hours the watch is not being worn? Would an auto-winder make a difference? Thanks for your help and advice. J. Thometz | ||

I think for a recent modern watch, you should expect +/- 6 seconds per day or better. Some differences when the watch is fully would to when the watch is at the end of its wind are normal. | ||

Zaf, Thank you for your explanation. So, would you recommend an auto-winder to keep the watch more accurate? Do auto-winders serve that end? One other thing: With respect to crown B, I find that on occasion the cities and second time zone do not advance as they should, i.e. in correspondence. Is this a problem that might be associated with Crown A? Thanks again. | ||

Unless you have some sort of caldendar watch that is difficult to quick set, I think winders are overkill. Usually the watch will run slower in a certain position like upside down. Once you figure out what it does and in what position you can compensate for the rate by putting in that position when you sleep. I don't know about you questions with regards to the cities function. | ||

I got my Master Geo in a month, and I am still testing accuracy, In the beginning, it loses 2 sec/per day, and now since I have no time to check everyday, it loses 5sec/per week, I am happy with this result. Be careful about the auto-winder, Geo only requires 800 TPD, and if not high-end winder, they will possibly over-wind your watch all the time, which may be bad to your watch in the long run. The Geo. time zone, I have never seen the problem you described, can you be more specific?? |
