Dear Danomar, my compliments: great catch, this is one fantastic Heuer.
I am lucky to have bought one in the past and ever since I got it it's been the one I've been wearing most.
It's both sporty and stylish, and goes down well with casual attire and a suit and tie likewise.

As for the bracelet I'd stick to the advice given by Peter: the Di-Modell is the strap for this one, it's cheap and exceptional value for money.
The bracelets, as Alex points out, are incredibly hard to find: in spite of the catalogue picture, the flat band one is the 'right'. I have never seen a picture of the brushed Carrera 510.523 with the Jubilee-type, which instead is the rule for the black PVD sibling 510.511 (another fantastic watch, btw).

Enjoy wearing this great watch in good health.
Cheers,
Fabrizio
