I don't really know what that is. I threw it in there years ago thinking it may be for a Speedmaster, Now that I see it again, I see that it may not be for a speedmaster. You will see 3 small sub register hands in the lower right. Two of them are white and one of them is steel.
So there is not a full set of sub hands for speedmaster unless you paint one of them white. That's all the bad news. All the rest is great news. There are some great alpha hands which fit Seamaster 321's.They are a bit short for Speedmasters. Of course many folks try to pass these off as Speedmaster hands. That's not how we roll here. There is a full set of hour, minute and all second hands for an automatic Speedmaster 176.001 with the orange center minute recording hand. Then of course there are a bunch of hour and minute tritium white baton hands for Speedmasters.
There are some very nice tritium sets, including one super nice second hand for 145.022. There are even 2 new old stock sets for 321 and 320. Auctiva Offers Free Image Hosting and Editing.
