For the full inside scoop on the 126600, look no further than this exhaustive review, written by Ben back in July of 2017. From the history of Rolex dive watches to notable past references and a full breakdown of the new model, the Sea-Dweller remains endlessly cool and a great watch for summer, above and below the waves. It's a long read, but what link else are weekends for?Click here to read: "A Week On The Wrist The Rolex Sea-Dweller Reference 126600".

In a similar revolutionary way, the ref. 1163 link "Siffert" came along in 1969 as the first white-dialed Autavia from Heuer. Taking its name from Jo Siffert, due to the watch's presence on the legendary driver's wrist back in the 70s, this particular Heuer chronograph was offered only between 1969 and 1972. As a later example, dating close to '72 in that range, the watch we have here is referred to as a "Mark 6."

There are shortages across the board for this very specific link set of timepieces, and that in turn has blown up the enthusiast and collector community, which exists most days in a combined state of anger, frustration, and disbelief, with the latter feeding directly into the former two.
