Re: COSC
In Response To: Re: COSC ()

thanks for clarifying that point about the average of the readings. my SMP chronometer consistently loses about 5-6 sec/day in each of the 6 positions, when averaged out to an 8 hours off-for-sleep period (ie: sometimes i have it off for longer or shorter depending on how much i sleep). i was just curious if
the COSC standard was on a moving watch, for example, on a winder, for 24 hours in a given position (and temp) or if it was stationary for 24 hours. if i leave my watch in a given position for 24 hours stationary, it loses only about 3 sec/24 hours.
thanks

: The full COSC test is more than just positions,
: it measures at different temperatures, too.
: Plus there are a number of specific
: measurements besides the often quoted +6/-4.
: So without the full COSC spec, which I
: haven't seen published anywhere, you can
: merely try similar test.

: Also, understand that he +6/-4 range is based
: on the AVERAGE of all the measurements. The
: watch is not expected to stay within that
: range under each possible position and
: temperature.
