Accurate? No. Their movements are too complicated. The Datograph Chronos were gorgeous, just not all that accurate. Not sure if they are still available.

If you want something more passable, the regular Langematick (non tourby), Saxonia and 1815 are all OK. They are simple watches that can use a standard Chinese movement.
The Richard Lange was probably the best, but not sure if it's still made.
