A neutron star is tiny, at an average 20km in diameter, but incredibly dense. Its mass is equivalent to 1.5 times our Sun – which has room for more than a million Earths. How does this set the backdrop to a review of the fêted Sinn U50 SDR, the first-ever Sinn with a waiting list? Physics and astronomy is an unusual starting point for a watch review, but stay with me…! Thanks to the generous engineers at Sinn Spezialuhren in Frankfurt, I have had the new Sinn U50 diver comfortably on my wrist for a couple of weeks, and the confusion started the moment I picked it up. Like the neutron star, it is small and rather heavy thanks to the HY 100 submarine steel construction; a compact nugget of a watch. A 40mm diver of mine on a tropic strap is 30 per cent thicker and weighs 90 grams, whereas this is a heavy 130 grams and very slender at 11mm. On its rubber strap it weighs only slightly less than my Tudor Black Bay Fifty-Eight on its solid steel bracelet, and that’s including the Sinn rubber being cut short to fit my twig-like forearm. In a word, it…
