What the Pelagos 39 doesn't have is a helium escape valve HeV or the standard model's "cut out" rehaut nor does it have the automatically adjusting trick dive
link clasp seen in the standard and LHD iterations of the Pelagos. Also thanks to the use of the
link MT5400 there's no date on the Pelagos 39. Ticking at 4Hz and offering COSC timekeeping
link and around 70 hours of power reserve the MT5400 is a solid movement that we've seen in other 39mm Tudors like the Black Bay 925.
