Santurce Guaraguao Time Only — Automatic Pilot Watch

Owners praise the Santurce Guaraguao Time Only — Automatic Pilot Watch as a versatile bargain with excellent specifications, highlighting its strap versatility, bright lume, and good customer service. The watch is noted for its solid feel and a secure screwdown crown, with one owner finding the 42mm case size good for a 7-inch wrist.

Overall, owners rate the Santurce Guaraguao Time Only — Automatic Pilot Watch highly for its value and luminous display.

Seiko Prospex Sea 1965 Heritage Diver's Watch

The Seiko Prospex Sea 1965 Heritage Diver's Watch is praised for its refined engineering and updated features, including a 300m water resistance and a 72-hour power reserve from the Caliber 6R55 movement in a 40mm case. Owners note its better build quality and interesting finishing with a mix of polished and brushed surfaces. The "Tranquil Teal" variant features a jewel-toned dial with a rippling-water pattern. However, some owners consider the price too high, and concerns exist regarding the accuracy of the 6R movements, with some reporting theirs run slow. One review notes a reflective dial that impacts legibility. On balance, owners and reviewers appreciate the Seiko Prospex Sea 1965 Heritage Diver's Watch for its refined design and improved specifications over previous generations, despite some reservations about movement accuracy and price.
