Question on when to service recently acquired batman GMT 116710

[JEM999]

Hello:

This is my first post here. I am very grateful for the wisdom I have found in this forum. I just recently traded in a yacht-master 37 and an omega aqua terra towards a 2017 GMT-II Batman. Because of this forum, I stayed clear of the 32xx movement and I'm happy with my decision even if it means only peace of mind.

My question has to do with recommendations for timing on servicing. My Weishi 1900 gives me the following data which I have summarized:

readings were done in the 5 recommended positions and are averaged

1) Full Wind:

average beat rate: +3.2 with a range from 0 to +7.71
average amplitude: 282 with range from 275 to 303
average beat error: .675 with a range of .6 to .8

2) 12 hour delay:

average beat rate: +3.71 with a range from -.57 to +8
average amplitude: 274 with a range from 258 to 294
average beat error: .74 with a range from .7 to .8

My readings represent a one time assessment. I'm not sure if it matters to do additional readings over a longer period of time.

So it looks like my amplitude is pretty good. I'm happy with that. The beat rate does seem to have a bit of a wide range. I guess this is a function of the beat error? The highest beat rates are obtained with positions that are crown left and crown down.

So, this 2017 watch has not been serviced as far as I know. Perhaps it is due for a service on age alone? Anyone have additional concerns based upon the data I have mentioned? One thing I do not want to do is incur undesirable wear on the movement. Overall, I'm really happy with this watch and I do want to take god care of it. Service now? Wait? Any urgency? Thanks in advance for any ideas or recommendations. Happy Holidays.

Kind regards,

Jon

I am not an expert so don't take my advice as expert advice just as a general purpose information. I am however a Rolex collector and enthusiast I have acquired quite a few Rolexes over the past 6 years or so so I don't have much time as far as the number of years goes but I have immersed myself in information YouTube videos reading the Rolex website diving deep through one layer to another layer to learn as much as possible listening to experts and being a part of this forum and another one. So from my perspective I have not bought a watch that has been 12 months old from the gray Market I believe everything that I have purchased has been within 8 months of the card date but that said I have often thought if I were to purchase a watch that were 5 years or more older the first thing I would do would be to send it to Rolex for service that would achieve two things first it would authenticate The Watch then I would be assured that my watch was as good as a new when I started wearing it. The watches that I have purchased from my authorized dealer I've read and heard people say that Rolexes are good for about 10 years without service but then Rolex recommends every 5 years to get a service. So bottom line from my point of view if I were to purchase a watch that were five or more years older from someone else the first thing I would do would be service it unless they provide service papers that show that it has been serviced recently. Just my two cents worth

Take my advice sell your Weishi 1900 as they can and will sometimes be a watch owners worst enemy.Just wear and enjoy your watch regarding service when its broken or keeping extremely bad time keeping, but depending on use service every 5-10 years is normal.

Great advice. Just enjoy your watch and service it when it no longer running to your satisfaction.

I think a rolex can go 10-15 years before needing a service. My 16710 hadn't been serviced in 20 years and when I serviced it still only needed a mainspring. Based on the stats you posted, the rate error and amplitude look fine. The beat error seems a little high but nothing major to worry about. For a 2017 watch, you have another few years before you need to worry about it I would say unless you notice something major in day to day wearing.
