Talk:COSC

Fine regulation and chronometer characteristics of a watch can be destroyed in seconds by a rough and inexperienced hand.
What is meant? A user banging around the watch or an unqualified watchmaker tinkering inside?

It could also mean shipping from testing facility to the factory. — Preceding unsigned comment added by 67.165.219.167 (talk) 03:25, 30 April 2013 (UTC)

Just another way to say mechanical movements are obsolete
Notice that the quartz standard is 0.2 seconds per day while the mechanical standard is -4/6 making the quartz requirement 20 to 30 times more stringent. Buying an expensive mechanical 'chronometer' makes no sense when available quartz models are so much more accurate and less costly. Wearing an expensive mechanical watch just tells the world you have more money than sense. — Preceding unsigned comment added by 75.68.48.123 (talk) 14:37, 30 August 2015 (UTC)
