Your criteria for an in-house movement seem to point to …

a surprising choice, one that many collectors do not yet fully appreciate. It's made in-house, assembled individually by master watchmakers, has contributed a huge chunk of innovation to the industry and if judged only by its timekeeping, it is one of the best. One owner has boasted on the internet that his watch is consistently accurate to one second a month. I'm talking about a self-winding mechanical watch which is available in various configurations, including a GMT with large date and power reserve indicator and  a power reserve of five days.. Production this year will be around 3,000 movements, because the company does not have more watchmakers who are qualified to work on it, but they are training more as fast as they can. Have you guessed what I'm talking about yet? If not, you may be surprised. It's Seiko's Spring Drive. I know that many collectors don't take it seriously because of its use of a quartz crystal to regulate timekeeping by controlling the speed at which it's glide wheel rotates, using magnetic  fields to do so. But since it is powered by a movement with a conventional mainspring and self-winding mechanism, it seems to meet most, if not all of your criteria for a watch with an in-house movement - but that may come as something of a surprise!

Thoughts on "in-house" movements and their reflection of the watch maker?

Clearly the discussion on in-house movements in less about accuracy and more about something else. Quartz is more accurate and as such would appear to be the right decision for buying the most "accurate" watch. Given this, the purchase of mechanical watch...

I actually can't get too worked up about the issue of in-house movements. What counts for me is how well it keeps time and how rugged it is. Most of my watches don't even have display backs. Start with the actual design process. The tiny independant is pr...

Seiko and Rolex...

If 100% in-house is the major concern, then Seiko makes the most parts in-house (everything I believe - someone correct me). If you want accuracy as well then the Grand Seiko is the answer. Otherwise, Rolex makes just about everything, and you likewise ge...
