In case you need a refresher, the 5168G was launched at Baselworld 2019 to a ton of buzz. This is the first mainline Aquanaut with a green dial, and it came on the heels of the nearly-impossible-to-find 5167A, a 40mm steel Aquanaut with matching green dial and strap. When Stephen wrote that initial story, the only auction result he might discover for a green 5167A was from 2015, when one offered at Sothebys for CHF 52,500.
