Both new RM 30-01s are a classic RM tonneau shape, the slightly wider variety (41.7mm width, not including the crown) with an arced case to ensure that it sits snug on your wrist (and at 17.59mm in height, this may even be snug enough to slide under your Loro Piana sleeve). Of the pair, one version features a case back, and bezel in satin-finished 5N red gold teamed with a case middle in grade 5 titanium, while the second is entirely machined in satin-finished titanium, which is hypoallergenic and, as all the RM-heads know, is super resistant to corrosion and shocks. Its grade 5 titanium caseband is fastened to the caseback and bezel using 20 spline screws – you know the drill – I swear I wasn’t going to include that joke, but I’m fuzzy after a long weekend.
