·Up for sale are three original flat foot logo / 24 tooth Omega crowns for early Speedmasters/Seamaster 300s. It's worth noting that I do not consider myself an expert on these, so feel free to DM me if anything seems off in my descriptions.
[Sold] #1. Nice 24 tooth / flat foot logo crown for 321 Speedmaster references
I believe this is referred to an A1 Speedmaster crown, correct for 321 Speedmaster references. Dimensions are 6.8mm diameter x 3.8mm thickness (4.9mm including protruding tube) and it has a 1.0 mm stem size. Crown is in very nice condition. The tube pictured was installed on it when I received it, and I've seen NOS crowns with a similar tube installed, so it's possible this is NOS. However, I received it in a crown lot so I can't confirm this. Asking $550.
[Sold] #2. Used 24 tooth / flat foot logo crown for 321 Speedmaster references
This crown appears to be the same as #1, except that the protruding tube is 4.2mm total height compared with 4.9mm for #1 and it's closer to 6.7mm diameter presumably due to wear. The tube has some visible damage and combined with the shortened height, I assume that this is an A1 crown except the tube has been damaged. The crown is clearly used and shows wear, see photos. Asking $250 (reduced from $300).
[Reduced] #3. Nice 24 tooth / flat foot logo crown for early Seamaster 300 references
Dimensions are 6.8mm diameter x 3.35mm thickness and it has a 0.9mm stem size. I believe this makes it correct early Seamaster 300 references (2913.14755.165.X, 166.X). Crown is in very nice condition, potentially NOS but I can't confirm. Asking $375 (reduced from $450).
