How set time in a colibri pocket watch?

is a colibri pocket watch gunmetal|||If this is a normal analog (dial and hands) watch,


pull the crown ("knob") out and turn it.





If the movement is quartz, it will most likely stop running


as long as the crown is out, and start again


when it is returned to its normal position.


Don't leave it out for more than a few minutes: some quartz movements


actually place a short across the battery when in this mode (!).


Better movements either shut off the power to the circuitry


or mechanically stop the rotor when the crown is out.


[Watch companies never tell you to which of these possibilities


your watch is subject, but if the watch originally came with a


plastic piece under the pulled-out crown, it is probably,


but not guaranteed to be, the shut-off type.]





If the movement is mechanical (wind-up), it will most likely


continue running with the crown pulled out,


but some mechanical ones are made to stop


(the official term is "hack") while being set.


With either of these, it is also best to push the crown back in


and allow the movement to run normally as soon as possible


(within a few minutes).





"Gunmetal" is not a material; it is a finish colour,


intended to look something like a blued firearm barrel.


The actual material of which the case is made is likely to be


some cheap mix of copper, zinc, and other elements,


commonly called "pot metal" because of its similarity to


the mix of leftovers in waste-pots at foundries.
