Hi there-- can anyone point me in the right direction to remove the stem from this SEIKO MEN'S AEROSPACE PILOT SLIDE RULE CHRONOGRAPH WATCH SND255P1. My 1st watch tinkering was on a miyota 8215 and it was relatively easy to remove with a little depress button! In this quartz movement, I am not find the same -- and not sure which right without forcing too much!

See pictures below.

Cheers
Mr T

Well hello again...looks like a nice watch...well it looks like right on the left pic...there is a little hole right below the screw there is the release...take a look in that hole..otherwise it is the brown looking pin to the right of that ...it will take a little fiddling and you will find it...God Bless John...

Could it be a lever release-I have at lease tone of those. Could you depress the lever(?) in the cut out to the left of the stem in these pics?

Hi there again
I've tried the black hole below the screw (assuming crown is north) and also the brown looking pin.. neither seem to work-- do you mean in the hole which seems to have a slight plate covering it-- i can see the an arrow and push inscribed here.

Cheers

Yep, that's the one I was thinking of. What happens if you 'push'? Who could resist such an invitation?

Now for the watch bezel

Hi there--- got it--- yes it finally worked although wasn't an obvious place under the plate but it worked nevertheless :)

As you can see I've now put a new crystal and bezel on. The bezel is very stiff and doesn't seem to turn-- I didn't see any small bezel spring or ring when I took the old one off :-( so not sure if I have lost that or not! Not sure how I can tell.

But at least looking good for a repair watch and i'm learning all the time :)

Hi there
I couldn't see any wavy washer or ball. According to skg 7548 there's no mechanism, just relys on snug fit. Although he said shouldn't be tight though. So perhaps i need some silicon grease?

yeah i'm pleased as I wanted to refurbish a cheap watch that I got from eBay and try my hand at changing the crystal and the bezel and this exactly gave me the practice I needed.

I guess almost ready to think about another project-- although not sure what ! cheers

I've got a new seiko SKX007K2-- thinking of perhaps modifying that-- although quite keen now to buy separate the parts to assemble my own mechanical watch :)
