Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
The Xeric NASA Apollo 15 American Automatic is praised for its unique space-themed dial design and its ability to deliver on its concept, with owners finding it aesthetically pleasing and a good conversation starter. Legibility is noted as not great by some, though the dial and face design are considered selling points. Owners report mixed reviews, with some appreciating the solidly made watches and their great designs, while others express doubt about the watches being made in the US. One owner found the design amazing but felt the execution was not at the desired level, though it was considered reasonably priced. The AmeriChron caliber X3.1 automatic movement is not as accurate as mainstream Swiss or Japanese movements. On balance, owners and reviewers rate the Xeric NASA Apollo 15 American Automatic well for its unique concept and dial design, despite some concerns about legibility and execution.
Owners widely praise the Sartory Billard SB04-E for its impressive and deep dials, with specific mentions of the 12 Soleil pattern and the Exquisite Blue Guilloché appearing to move like water in the light. Reviewers highlight its sensible 39.5mm size and 100m water resistance, noting the overall composition looks more expensive than its price. One owner points out slightly sharp edges on the caseback and suggests a more domed crystal. The watch utilizes the La Joux-Perret G101 automatic movement with a 68-hour power reserve. Overall, owners and reviewers rate the Sartory Billard SB04-E highly for its unique dial work and value proposition.
