Filippo Loreti Watches The Riddler is described by owners as a cheaply made watch with generic designs, with some suggesting it is a Chinese-made item valued under $100. One owner reported that multiple Filippo Loreti watches, including The Riddler, stopped working within a year, and customer service provided no resolution. Another user noted that images of the watches were removed from the brand's Instagram, hinting at potential licensing issues, and heard claims of the brand being a scam selling Chinese watches as Italian. On balance, owners find Filippo Loreti Watches The Riddler to be a cheaply made item with generic designs, with significant concerns raised about product reliability and customer service.
The Seiko Prospex Sea 1968 Heritage Diver's GMT is widely praised for its build quality, finishing, and value, with owners noting its comfortable wearability and attractive aesthetic, particularly the silver/white sunray dial and blue ceramic bezel. The improved bracelet clasp with excellent micro-adjustment is a recurring positive point. Some owners report accuracy figures of +3 seconds per day or +/- 5 seconds per day, exceeding the movement's stated range. However, the GMT functionality is considered secondary to its dive watch capabilities by some, with the GMT scale being difficult to read and the caller-style GMT movement being a drawback for certain users. The dial contrast is also noted as lacking by some, and the crown at 4 o'clock is undesirable for a few. On balance, owners and reviewers rate the Seiko Prospex Sea 1968 Heritage Diver's GMT highly for its blend of dive watch character and GMT functionality, offering significant features for its price.
