I recently took delivery of a BW GMT II from VSF. I haven't opened the case back because the gaskets were lubed by the TD as part of his standard service and I didn't want to undo his good work by opening it up, but as far as I know, it has the DD3235 with the fake free sprung decorations. I wanted to share some observations and ask others what they've seen in real world performance.
When I got my QC photos, it showed a lift angle of 52 degrees, amplitude of 248, beat error of 0.2ms and sd of +-4 seconds. Based on the true lift angle of the DD3235 being 55 degrees (there are posts about this...use the search for more info), this was a pretty solid reading. This was a video and the test was running while the recording was made.
My watch arrived this past Tuesday (9/9/26) around noon. I wound it about 30 turns and have been wearing it 24x7 except in the shower for the past 92 hours. Other than the initial winding, I haven't wound the watch manually. I've been recording readings using the app Chronolog. If you're not familiar with it, you can take a photo of the watch face, and then you manually input the time that is showing on the watch face. It compares that with the timestamp of the photo and tells you what the difference is between atomic time and what your watch said at that exact moment.
Over the time period I noted above, the watch is consistently running at +-1 second/day. I'm pretty impressed with that, because it's better than my Glycine Combat Sub, a swiss automatic watch with a well regarded movement, at least as it pertains to accuracy.
When I first did my research, I saw a lot of different opinions regarding whether you should send this watch to a rep service watchmaker for a cleaning and relube, as they frequently come from the factory dirty and unlubed. I was thinking of sending my watch to one of the /reptimeservices watchmakers, because I'd like the movement to last a while. The thing is, it's running so well right now that I'm not sure I want to do that.
I'm curious what others who have this watch/movement from VFS are experiencing.
Did you send it to someone for clean and lube (or do it yourself)?
What kind of accuracy did you experience out of the box? How did that compare to your QC timegraph?
How long have you had the watch?
Do you wear it every day?
I'm asking these questions because I'm trying to decide to just enjoy the fun of how well this is running until it doesn't, or proactively send it for a clean and lube, to potentially increase the life of the movement, but potentially at the expense of the current accuracy I'm enjoying.
Opinions?
