    JLC 1000 Hours vs COSC

    Evo malo usporedbe:

    The first thing is that the Master Control 1000 hours (COSC 360 hours) test is carried out only when the watch is fully assembled, including casing, hands and dial, not just the movement (COSC, movement only).
    Accuracy must be within the range of -1 to +6 seconds per day (COSC -4/+6 for Gents and -5/+8s for Ladies)
    Power Reserve Test: under intense activity and when in low activity simulation (COSC not tested)
    Functions and aesthetic inspections and test (COSC not tested).
    Knocking test for the balance (COSC not tested)
    Accuracy under normal and fully wound. Test in 6 positions and in cyclos (COSC 5 positions, normal condition only)
    Water resistance test at least 5 ATM (COSC not tested)
    Shock Resistance test with 20,000 small simulated shocks (COSC not tested)
    Resistance to thermal variation between 4 degrees to 40 degress centigrade (COSC 8 to 38 degrees centigrade)

    Za pohvalu je ovo testiranje ali jedan je COSC kao nezavisno tijelo i samo njihov sertifikat daje pravo nekom modelu sata da se zove hronometar.
