COSC (1999) Quartz chronometer Swatch


None aside from @Eeeb bought a replica of this watch (in 2007).

@ppaulusz commented: “This motion was awarded the COSC for quartz earlier than 2001 and is not as tight as the brand new normal since 2001.”

@Eeeb then reported six months later:

I bought a Swatch Watch Irony that was made the identical 12 months because the Swatch Watch COSC Chronograph (because of its excessive age), chopped each up and saved them collectively. They shared the identical thermal atmosphere (and nonetheless do… I am unable to carry myself to put on the chronograph and the Irony does not swimsuit my style… I simply bought it for this experiment ;-))

In about six months, the COSC chronograph gained 13 seconds.

In the identical interval, the management clock gained 38 seconds.

It is only a single information level… nevertheless it does not negate the belief that the actions chosen for COSC certification have been extra correct than the usual.

🤷‍♂️
