Harry,
No - I had not seen this before and I was at Tempus 2008 looking at the brand executives' wrists
I must say that it is a change for Sinn that is usually associated with tool-watches for Land, Sea and Air.
This regulator somehow reminds me of early Ulysse Nardin watches in the revival period after Mr Schnyder took over......or hints of early Chronoswiss under Mr Lang (without the coin-edged bezels). Maybe it's the classic proportions that they all have in common. Very nice!
Also clean and crisp picture - what % was original shoot and what % was PhotoShop?
Regards,
MTF
