So do you think this model is a good buy? I like the size and parts list.Ten days going and seems to doing much better compared to the RONDA specs.
ACCURACY: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.
