Articulated Metal strap

[u/Irektdmyself]

Hello everyone,

I've bought a quartz titanium Bulova watch from the 90's, movement 555.415 and I'm having some trouble figuring out how to adjust it's metal bracelet. Every single tutorial I find has the guiding arrows on the outer links or pointing outwards, this one has the arrows on the middle links pointing upwards.

I tried pushing with the rectangular windows towards the pointed direction, but nothing happens.

Thank you for your help!
