Wittnauer, a Longines sub-brand, produced lots of very high quality watches. This particular reference 800 is a perfect representation of their high quality and attention to detail.
The case is crisp and thick, made to be durable. The dial is a work of art: although simple it truly represents a perfect balance between the three registers and the simplicity of it. The hands are unique to this model, having a pointed end and being blued steel with radium lume inside them. The Valjoux 72 inside is fully signed and one of the best I have ever seen.
If this was not enough, the watch comes with its original box (though no papers).
