Same 26.5mm steel case as the Diamants version, minus the stone-setting — reference L81114716 swaps sparkle for roman numerals on a silver dial, which is the more conservative, arguably more durable choice if you don't want to think about loose stones down the line. It's still an automatic movement on a steel bracelet, 30m water resistance, so the practical envelope is identical to its jewelled sibling. On my scoring sheet this is actually the better value-per-dollar entry in the sub-line: you get the same case architecture and movement, just without paying the diamond premium. For a first PrimaLuna, this is the one I'd suggest trying on.
