Review 2: ORSA Quartz Chronograph Miyota OS60
The Crown and Pushers
The crown is unsigned. Not a big deal for me, I am not a brand "freak". Although I admit I Iike that new Orsa logo with the folded upper right corner of the "O" and that "folded O" would be very well suited to decorate a crown. But for this utilitarian package, an unsigned crown is perfect too.
There is something very positive to mention about the crown. It is very high and sufficiently big. And personally I love big crowns. The high crown makes it very easy to set the time and this crown has very good proportions in my eyes.
The pushers' action is smooth and clearly defined. Miyota did a great job here. The first push of the 2 o'clock push button starts the chronograph. The second hand will now show the elapsed time while the second sub dial rotates once a second during the first 30 seconds and displays 1/20th of a second if the chronograph is stopped. After 30 seconds the seconds sub register at 6 o'clock stops (to save battery life) but if the chronograph is stopped, it will jump to the 1/20th seconds.
A nifty feature in my eyes is that the second sub register can display the running seconds. Simply press the 4 o'clock push button after the chronograph has been reset and the second sub dial will show the running seconds.
A second push on the 2 o'clock push button stops the time and this action has no click. This is a characteristic of the OS60 and if you are a frequent 7750 user you will have to get used to it. The Caliber OS60 allows start-stop-start-stop sequences but it does not take split times. You simply press the 4 o'clock push button to reset the chronograph, independently whether the chronograph is running or stopped. A second click on the push button at 4 o'clock will switch the display of the sub register at 6 o'clock to display running seconds. The action of the push button at 4 o'clock has a defined click for its first and second push and like the push button at 2 o'clock no click for its second push.
