Good Morning
Please can anyone suggest a watch opener to crack the case back of this watch?
I have found on the watch manual it says to prize up the cover at 12 & 6 o’clock locations on the edge of the cover but it seems stuck steadfast.
I want to change the battery and see it it works.
Lastly there seems to be a Mode button missing, is this an easy fix or not and if so is there anywhere that sells missing parts for a watch this old?
Thanks in advance…

Seiko Case Back

Hello,
I got this swatch chronograph watch from my dad and one of its pushers is gone.
I did some research on YouTube where I found some videos explain how to replace it. What I want to know is whether there is another way to release the crown / stem besides taking off the dial first or pulling it out directly with arched claw tweezers. Have any of you done using the arched claw tweezers technique? Did it work well without damaging the calibre or machine?

Meanwhile for the chronograph…
