good (fri)day to you 
does anyone know what i'm talking about please:
one of our cats* stole my watch — which is my ecg, o2 sensor, and heart rate monitor — from its hangy place last night while i was in the shower and dragged it around (including down three tile stairs). the screen now has a small crack in it, and as replacing the screen will cost more than an as-new, second-hand** replacement watch 
, i'm trying to repair it.
husband is sure that there's some kind of glue that will go into cracks in glass and fill them invisibly. he says it's wetter than water and just spreads out where it needs to be when applied. have you heard of this?
if anyone could help with this, that would be amazing.
thank you
(and please boost, if you don't mind)

**i mean most watches are second-hand watches ... 
@moonrabbit windscreen repair kits for cars include it
@moonrabbit might screw with any touch-screeny stuff though, not sure how it interacts with coatings on glass I'm afraid
@evilstevie
thank you. the stuff he's thinking of is thinner than that, but along the same lines. the crack is right at the edge, so theoretically not somewhere i touch?
tyvm again.
@moonrabbit found this stuff - am UK here, so regional links may need a shuffle:
loctite do a glass glue, should be searchable, this is one of the alternatives
@evilstevie
ooh thank you! that looks very interesting. and we could always get it sent to family in the UK for shipping on ...
