No jewels?!
That’s right. Zero jewels aka 0 jewels aka no jewels.
Is this watch in my Invicta?
Which model of Invicta do you have?
Seems there is no way to ‘reset’ the chronograph minute ‘sub hand’ or the ‘Hour Sub hand’ (to zero). the only thing that can be RESET is the sweep second hand. this seems strange?? anyone have other info on this?
Are you referring to resetting the chronograph after a battery change? So you push start, stop, reset and the hands do not line up at the 12:00 position? Please provide more info if possible.
that is correct. the ONLY hand that can be ‘reset’ to ‘ZERO’ (12 o’clock position) is the Sweep second hand (pull crown out to 2nd position and using button A move hand in clockwise motion until it’s pointing at 12 o’clock). however the ‘SUB DIAL hands” (for chrono minutes and Chrono Hours) cannot be moved and are NOT pointing at the 12 o’clock position. how is this accomplished? the Miyota manual does not provide this instruction. 🙁
Sometimes you can try in different crown positions. So pull it out one click to the date setting position (position 1) and try the top and bottom buttons. If that doesn’t work, try it again in time setting mode (position 2). These directions are more geared towards Ronda movements, but might be worth checking out: https://www.keepthetime.com/blog/how-to-set-an-invicta-chronograph-back-to-zero/
Yes, thanks. tried that, those have no effect on the sub dials. 🙁
Hopefully you will be able to get it reset to zero with the above instructions. Oddly, instructions for the OS10 chronograph from watch brands only mention the ability to reset the main chronograph hand. For example: https://jackmasonbrand.com/wp-content/uploads/2016/10/JM_MiyotaOS10.pdf and http://images.heine.de/asset/mmo/12813698.pdf. Did you try the 4:00 pusher?
Yes, that is the same conclusion I found. only the sweep second had can be reset (strange). I wonder in the factory how it’s done? that’s what I was looking for the ‘factory’ short cut. maybe shorting some pads on the back of the movement? Not sure. thanks
Instructions from Casio for this caliber (they call it Module 2328) do specify how to reset the hour and minutes on the chronograph.
It is used in the AMW330 and MSY-501 models, amog others. Unfortunately mine seems to be damaged (which is how I found this forum) and I cannot test this.
they say my Caterpillar (watch) DT.163.20.211 has this type of movement, but I am not watch-pro, so I am not sure 100% 🙁
