I had thought the ETA 2836 was just the day/date version of the 2824, but recently I looked at the Bernhardt Corsair, which uses the 2836 but only has the date. If one wanted to only include a date complication, couldn't you just use a 2824?
Moreover, reviews of ETA 2836 movement watches I've seen (such as the Corsair and batch I of the Prometheus Ocean Divers) seem to indicate a pretty consistent accuracy of +/- 15 secs per day, which is generally somewhat worse than 2824 reviews I've seen. Admittedly, these reviews are pretty anecdotal, which is why I'm posting this.
So my question: what are the differences between the ETA 2824 & 2836 movements? Do both of these movements come in varying grades? What is the rough price difference in cost of the movements? And finally, do both generally return the same level of accuracy?
thanks for your answers,
