Speedmaster Professional 3861 Sapphire 310.30.42.50.01.002 https://imgur.com/a/zjBeM5O Selling my used Speedy pro. This is the latest generation of speedmaster professional that uses a sapphire crystal on the front and back, hence the often seen nickname “sapphire sandwich.” 42mm, manual wound co-axial movement, elegant yet sporty bracelet and clasp. When paired with the history, this modern interpretation of the speedmaster hits hard. Case and bracelet show wear from regular use over the past couple of years. Movement is running very well as indicated by my timegrapher. Asking $5675 shipped in the USA. Not looking for trades. I can accept a wire or payment through zelle, Venmo, cashapp. I can’t take PayPal. I have extensive history buying, selling and trading. Face to face in the northern SF Bay Area is a possibility. Thanks!
