Horological Machine No. 5 RT retains all the key features of the HM5: a hand-finished automatic movement with bi-directional jumping hours; a vertical time display reflected and magnified by a sapphire crystal optical prism; 'light convector' flaps which allow to charge the superluminova hour and minute discs and to compensate for the higher weight of the external red gold case, they've modified the inner protective compartment from stainless steel to titanium. While HM5 RT has a generously sized 51.5mm x 49mm case and gold is known for its weight as much as its beauty, thanks to the discrete use of ultra-light titanium, HM5 RT is a very comfortable machine to wear.
