Any of the following would be instant buys from me.
Tudor: Pelagos 39 in Blue; GMT 58; Black Dial Black Bay 36 on Oyster without crown tube; Black Bay 58 with updated non-rivet bracelet.
Rolex: Brushed oyster GMT; 20mm lugs on Explorer 36, or single baton version of OP 36.
Grand Seiko: Tons of watches I like that are just too big/thick for me. Just waiting for the right design to come in their 38.5 mm case.
Omega: Modern Aqua Terra 38 with brushed bracelet option.
Oris: Waiting for right dial color for me in 38mm big crown.
There are so many watches out there that would be perfect for me with one small tweak. Luckily, I am more than happy with some imperfection, and I can save a lot of money on watches that get crossed off the list.
