I had owned one and pruchased on 1995/6 and it is simple and very beautiful. there use ETA 2482-A1 and Omega modified and become 1142 as the in house movement. I had already used for 16 yrs and still function well. In recently years, alot of manufacturer design and build 3 hands watch eg. seiko,etc but I still perfer this one. it is really reason price at that time. Thought out the 16 years, I only sent for servicing one time and it it very accurcy. old technology may be more realiable.
