So you've got the QC images or your brand new best replica, like, ever, with that incabloc you always dreamed of, as swiss as cheese, but what about your timegrapher results? What dahell are those? Presets Beat Number Frequency, the vibration of a movement. The number of balance wheel swings per hour or how many times the watch ticks per hour. This is a preset, depends on the watch you order. 14,400 bph = 4 beats per second 18,000 bph = 5 beats per second 21,600 bph = 6 beats per second 28,800 bph = 8 beats per second etc Lift Angle The angle the balance passes through while interacting with the pallet fork. Important to be set correctly in order to calculate the Amplitude. This preset is per caliber specs. Most modern watches have a lift angle of 50 - 52 degrees. Generally lift angles range from 44 to 58 degrees. Some other settings are present, for instance Gen co-axials angle is 30 degrees. Results Rate How fast / slow the movement runs (in seconds per day) great : +/- 5 s/d acceptable : +/- 12 s/d If higher / lower? It is possible to adjust this yourself or ask your dealer to nudge it a bit. Amplitude The measure of the amount of rotation in the swing of the balance wheel, in either direction. Amplitude is higher when a watch is lying flat and usually falls when the watch is in a vertical position, due to increased friction. Amplitude can also fall as the watch winds down and the mainspring delivers less power. Amplitude is a good indicator of the movements health and if is too high or too low, or that changes too much in different positions, can indicate a problem with the movement. great : 270-310 acceptable : 250-270 If higher / lower? Ask for a different watch or have your watch serviced Beat Error The amount of time by which the duration of swing differs from one side to the other in the oscillation of a balance wheel. Generally speaking to get a beat error of zero, the roller jewel in the pallet fork must be perfectly centered. great : 0.0-0.5 ms acceptable : 0.6-1 ms If higher? Ask for a different watch or have your watch serviced. * Please note that if you are reading your QC from the dealer, you will generally receive only the results of the watch lying flat. All the above recommended measurements are from that position. The measurements in other positions may vary1 point

Great stuff! At Uni we used scanning electron microscope. That was fun! Thats another cheap USB microscope. I have never used one. http://www.amazon.co.uk/Veho-VMS-001-20-200x-Magnification-Microscope/dp/B001ACKIUO/ref=pd_sxp_f_pt Seems like a good idea to have the zoomed picture on Your screen instead looking through ocular, it gets tired after while.1 point

I got tired of it on the steel band, and thought I'd try something different. It must have worked, I've been wearing it for the last 2 weeks! Here it is on a boring old steel band, to keep everyone happy. And a photo before I swapped it to the tropical dial, this was the "radial" dial from its earlier life.1 point

My favourite is the first watch I got for my 4th birthday. Still have it. Other than that I think it's my uPO pumpkin but haven't worn it in years sins the crown stem issue, or my daily beater PAM 111.1 point

I would say that I keep coming back to the AP Diver. Something about the beautiful simplicity of the design, and the heritage of the name.1 point

I did the BK suggested build. Not franken, but really turned out great. http://www.rwgforum.net/topic/144657-making-a-gen-style-16710-case-out-of-a-16570-case-and-tw-bezel-assembly/?pid=1089607#entry10896071 point

Good call Deckard. I would have said possibly a Breitling Chronomatic, not like him to stray from the brand. But for sure the Autavia. Nice1 point

I have a few favorites but this is certainly one of them. Custom colorless AR from Sunnydale and VAC relume. The dial has some small tells but the crystal and lume are awesome. Just screams quality. I also really like my TC sub and a few others. Hell I can't choose, that's the whole damn problem with this hobby.1 point

This is a common 'feature' of the 2836 GMT conversion. The GMT hand 'slips' and loses sync with the hour and minute hand. There is a really easy fix to get it back working again without dismantling the watch. It's not permanent but it will work for a while. Adjust the GMT hand to where you want it, relative to your hour hand. Then set your time and scroll through a day or so. Just turn the crown and advance the time for 24 or 48 hours. It will get the gears back in synch and you should see the GMT hand working perfectly while you scroll through your time. It should work for a while. Whenever mine would slip out of synch that little trick would usually get it back working again.1 point

After you set the gmt and time, try going back to position 2 on the crown and setting the date. So make sure you set date last basically - see if that helps. If it doesn't it may also just be that they left out the dial washer or that it needs a little more bend in it to keep friction on that Gmt hand gear Sent from my DROID RAZR using Tapatalk 21 point
