Step up to 30mm and the PrimaLuna starts to read less as a discreet dress piece and more as an everyday watch that happens to look formal — reference L81134716 keeps the automatic movement and stainless steel bracelet, still capped at 30m water resistance. The extra 3.5mm over the smaller case doesn't sound like much on paper, but on the wrist it changes how the watch photographs and how confidently it fills a cuff opening. I'd flag this size as the sweet spot in the line for anyone who wants one PrimaLuna to wear most days, not just for occasions. Nothing exotic in the spec sheet, but nothing to complain about either.
