Well as the title say's this one is about settling time you might have notice on the wruw the other day I had a new 70's Swiss dive watch call Trafalgar well it been well used there some rub to the world names and it had a fair amount of d.n.a on the case mainly between the lugs people tend to give them a quick once over but forget there for some reason .

I some time wish they would leave them alone,the amount of watches where you can see where some one has damaged it trying to clean it or the old scratches on the back where they want to do a movement shot and they ant got the right tool so in trying, scratch the hell out the back .. as the scratches always seem fresh to me

Well maybe we have all done that at the start, I have been guilty of not using the right tools to start with ( remember one tool I made was a piece of metal with some holes drilled in it with a bar that screwed in to form a back opener well it sorta work most of the time but when it did not it was not a pretty sight it would end up with me or the case back scratched to hell )

Anyway's getting off the point so the diver watch so it arrived while cleaning the strap notice it was split think the d.n.a was holding it together most of the time I would bin the strap might keep the buckle if half decent so no biggie ...

Wound it up no action but gave it a technical tap or three and started and has been running none stop since great I hear you say well yes for a watch of about 50 years old that is really good ..

But within ten minutes it was running 10 minutes slow last time I had one like that it conked out .. so got on to the seller just to say not sure on this one mentioned the faults his response about the regulating arm was funny and his it keeps very good time ( not just good very good amused me in the ad ) he did say well yes it was running a bit slow
Now to the point of the thread yeah you knew I would get there sooner or later after all it is me

Settling time...

On the wrist most of yesterday it was running 12 minutes slow so as I said made the seller aware ... and took it off and put it upright on my side table as I said it has run none stop but in this position over last night and through today it has slowly creep closer to the right time as set to p.c it's down to 2/3 minutes so maybe just needed the settling time ...

If I get this sorta time on my wrist then I can live with that or get it service at some point ..

But the variation was weird hmmm ant had one do quite that before be fun to see what it does tomorrow on my wrist ...

Will do a couple of pic's tomorrow to see what it is doing through the day to see

So what fun stories have you got about weird time dilation on your measuring devices

As always Ismy

Breaking out the maths


Settling time

Settling time is the time required for an output to reach and remain within a given error band following some input stimulus.
The settling time of an amplifier or other output device is the time elapsed from the application of an ideal instantaneous step input to the time at which the amplifier output has entered and remained within a specified error band, usually symmetrical about the final value. Settling time includes a very brief propagation delay, plus the time required for the output to slew to the vicinity of the final value, recover from the overload condition associated with slew, and finally settle to within the specified error.

Systems with energy storage cannot respond instantaneously and will exhibit transient responses when they are subjected to inputs or disturbances.
