Hello All! I have an Omega Speedmaster Professional 3570.31 "Mitsukoshi" for sale. Runs great and all functions work as expect. A very clean example of this reference. Please take a look at the photos for condition. I have verified the serial and it is indeed a real Mitsukoshi not a put together piece. Only 300 of these were made at factory. Only getting harder and harder to find. *Only comes with what is shown in photos unless stated in ad *Service history on the watch is not known unless stated in ad - watches are checked for timing & amplitude *Watches are preowned so may have very minor wear unless stated in ad of any other marks Watch Description Brand: Omega Ref: 3570.31 Material: Stainless Steel Crystal(s): Hesalite Movement: 1861 Diameter: 42mm Accessories: Both Omega boxes, card holder, manual, warranty card Condition Movement: Runs strong and all functions work as should Crystal(s): Great and clear (excuse any little dust particles) Case: Overall Great Condition Bezel: Overall Great Condition Bracelet: Currently 7 1/4 inches inches (if more are needed can be supplied at cost) Asking 23500 shipped. Prefer face to face in NYC and local buyers get priority. References available by request or in the feedback section. Also search for “Kringkily” on popular search engines to find many reviews. I am a watch collector and I am not affiliated with any brand. I guarantee authenticity.
