As mentioned the U50
link is 41mm across 11.15mm thick and 47mm lug to lug. Lug width is 20mm and the
link U50 has drilled lugs woohoo! making strap changes nothing short of a breeze. Inside that now smaller case and
link covered by a solid case back Sinn has fitted the U50 line with Sellita's SW300-1 a Swiss-made automatic movement with a date function. The SW300 is meant as direct competition for the higher-end ex
pressions of ETA movements like the 2892-A2.
