This is a NEW ERA cap (9FIFTY) in collaboration with OMEGA's "SPEEDMASTER." Size: SMALL/MEDIUM (approx. 55.8cm - 59.6cm) This special edition was created for the 50th anniversary of the Apollo 11 mission, which went to the moon with the Speedmaster, and was distributed only to those involved. These types of items can sometimes be difficult to wear stylishly, but this one is quite fashionable and suits any style. Highly recommended! A must-have for Speedmaster fans! I think you won't be able to buy it again if you miss this opportunity, so those who want it, first come, first served. I think the resale value will be good too.
