The 3130 runs at 28,800 vph with about 48-hour power reserve, matching the 3000's frequency and power characteristics. The improvements are in precision and environmental resistance, not in the basic operating parameters.

The cleaner comparison is architectural. Caliber 3000 was already a modern high-beat automatic, but the 3130 adopts the 31xx layout: a full balance bridge in place of the 3000's balance cock, plus Microstella regulation, the construction collectors associate with later service robustness.

COSC chronometer certification appears on the dial throughout the run.

The 114270 dial is consistent across production. Black lacquered surface, applied 18k white gold indices with Super-LumiNova fill, applied 3-6-9 Arabic numerals, "Swiss Made" below 6 o'clock. Mercedes hour hand, baton minute hand, lollipop seconds hand.

That consistency is also an authentication trap. The 114270 dial gives none of the quick generation splits a 14270 does: no Blackout dial, no tritium-to-LumiNova text change, no late single-word "Swiss" dial. On a loose or poorly photographed head, construction details do the dating rather than dial taxonomy.

The only dial-adjacent change is the rehaut. Early production carries a plain, smooth inner bezel ring. Late production is engraved with repeating "ROLEX ROLEX ROLEX" text and the serial number at 6 o'clock.
