Thank you all for helpfull posts
I eventually got myself a Pebble Classic from web auction.
Saved about ~20 euros of price of a new.
Damn, I forgot to hit the subscribe button as now to think about it I should had invested in warranty also.
Hmmh. I hope mine won't loosen up anytime soon and the watch lasts longer than Sony MBW-150.
Now I'm using pebbled but waiting for a rockpool gui .
