Ten days going and seems to doing much better compared to the RONDA specs.



According to official documentation by Ronda, the calibre R150 is claimed to have an average accuracy rating of +/- 12 seconds per day with a maximum deviation of rate up to 30 seconds per day. Isochronism after 24 hours with +/-20 seconds per day. Ronda tests each movement in two positions at the factory. The R150 is equipped with an index system regulator for fine-tuning accuracy.
So do you think this model is a good buy? I like the size and parts list.
