For sale I have a so called Baby Tuna, Seiko SRP637 with the orange dial from another Tuna version the SRP251. It was worn only a handful of times and the watch is in excellent condition with very little light wear.

IT is large but thin and wears well with the included bracelet which is long enough for 8 1/2" wrists. Comes with the original box. Runs great and both bezel and crown are smooth operating.

Asking $345 net to me shipped in the USA. Open to offers.
