One of my "regrets". Early Panerai's days for me. I bought the 309 (wrong mentor) without knowing the existence of the 322. Not long after I saw a 322 and I suggested a swap with the seller 309+5K Sin$ and was turned down. He wanted Sin$10K no negotiations. I told him to go take a running jump in the lake and regretted it ever since Lollllllllllllllllllllllllll
