Sinn 240 ST Review
Last year at Basel World, Sinn announced a handful of curious and unexpected watches, from the diving-pilot's EZM 3F to the cleverly vintage 903 ST B E. But perhaps the most surprising was the 240 ST. Utilizing a case that dates back to at least the 80's, this barrel shaped tool-pilot is both new and a throwback. For those familiar with Sinn's line and history, you'll immediately note that the case comes from the revered 140/142 chronographs. Originally powered by the Lemania 5100, these rugged chronos are collector's pieces not just for their style, but also for their historical significance. As discussed in this article here, the 140/142s were, for a time, considered to be the first automatic chronographs worn in space. Sinn has since reissued those watches with their in-house modified Valjoux 7750 movement, the SZ01 and packed them full of their in-house tech. As expected, they command a demand a price of over $4k.The 240 ST is the first time this distinct barrel case has been used

Nautilus 40th Anniversary - Monday is the big day
Looks like Monday could be the big day for the launch of two special Nautilus watches to celebrate the 40th anniversary of the Nautilus. My money is on one in stainless steel and one in gold. I am hoping for a perpetual calander model. Let's wait and see.
