According to the Ronda website, this caliber 519 features:

  • Repairable metal watch movement
  • Power saving mechanism with pulled out stem: Reduction of consumption approximately 70%
  • Interchangeability: All versions 11½”’ with same movement height 3.00 mm and stem height 1.50 mm
  • Very powerful stepping motor

An interesting thing about the Big Date complication in this Ronda caliber 519 is that the date does not flip to 01 after day 31. It keeps going to 39, then flips to 00, then to 01. This will require you to set the date every month, and not just on 31 day months.

Replacement prices were found online from $11.95 to $16.95 USD.

Beautifully written, everything I wanted to know, and only partially knew. Just got a Mondain Big Date 30303 for a rock bottom retail £128.00, so about £8 for the movement, bulk buying. I know it is not as simple as that. I like it.

Found on the Renato XTR Diver & some Victorinox watches.

Seriously, who greenlit this movement? 39 Day date wheel cycle, what a joke.
