This is a genuine Hermle model 1050-020 with STANDARD STAGGERED ARBORS, Triple chime, 8 day, wind up movement, that has been rebuilt to include cleaning, lubricating, bearings replaced that were worn, 3 new mainspring barrels complete and complete testing. It comes with what is described and nothing more. This movement can be exchanged out for your existing movement cheaper than a new movement.
It helps greatly to have some mechanical abilities, but if you have questions contact me for help. Please use my free support offered. NOTE: There are several things that will need to be done in the process of switching movements.
