I recently picked up a 50s era bumper wind Omega Constellation that I had returned to Switzerland. I received the watch back in stunningly beautiful condition, with a bag full of parts showing me that perhaps the majority of the movement had been replaced. The dial, while left original, must have been cleaned and each of the faceted broadarrow markers were clearly polished; whether they were removed and polished or done on the dial, I don't know, but they positively sparkle.
This is the second time I have sent a vintage Omega to Bienne for service and the second time I received something back that exceeded my expectations (the first was a Speedmaster 125). They previously restored a gold dress tank, which my grandfather gave to me, having received it as a gift from his younger brother some 30+ years earlier.
While the Omega marque may not command the same respect as other brands popular among watch aficionados and consumers, it certainly commands my loyalty.
