I had one of my watches (Longines Hydro C.) on the timegrapher, and in dial up position it made a rather weird fluxation.
Stabilizing at around +003 and holding this rate for 20 seconds or so, suddenly and only for a fraction of time, it jumps down to -13, for then fluxating - just like that - up to +003 again. Then it stays like that for about 20 seconds, for again jumping to -13 and back to +003. And so on and so forth.
Why is this? Is this normal?
It could be mentioned that this watch has held an accuracy while worn about 1.2 s/d, but after using the snowblower (and sadly forgetting to take off my watch) which shakes and rattles like crazy, the watch has lost one second. I am thus worried that this might have impacted the performance of the watch.
Is my fears justified, or is such influxtions rather usual? I have no pictures for the moment of this weird reading. I used a witschi watch expert timegrapher.
Thanks in advance for your thoughts!
Really? 0.01mm? Maybe inches??
I just grabbed a largish looking one out of the packet. The head diameter was 0.6mm and the pin length (minus the head) was 2.3mm.
The packet really does have quite an assortment with different head and pin lengths and diameters.
I would send you one if you knew exactly what you needed, but some of the heads are tapered and some straight, so if this sounds about right then you might find it best to get the assortment to choose the best fit
