Zenith Sporto with 40T movement, one of the finest ever made by Zenith, maybe second only to 135. Serviced just before I purchased it here on OF in July, 2019 Case is all stainless steel, unpolished, screw-in backlid. Pretty sure this one dates to the 1960's. I purchased a nice DeBeers leather strap for it as soon as it arrived and as you can see it hasn't been worn much while in my possession. Case Diameter: 35mm ( Would like to get this one sold before the New Year! ) Price: $399 or best reasonable offer, plus $22 for insured conus shipping. Will ship to other locations if the buyer is willing to pay the additional costs over $22.
