I have a small wrist and reduced suits me best! And way cheaper too! 😁
I hv 3 speedmasters. 2 pros (3570.50 & HB-SIA) and 1 redux (Jap limited edition 1957 Panda). The pros are indeed at a different level in terms of build quality. But the redux is generally well built and good for smaller wrists. In terms of wrist time, all 3 get about the same.
