Owners + reviewers, side by side.
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
The watch features impressive luminescence and a high-beat Miyota 9015 movement. Reviewers questioned the value at the $659 price point.
The BOLDR Supply Co. Enigmath Sinharaja is praised for its functional slide rule bezel, operated by a screw-down crown, and its overall wearability, with owners noting its comfortable size, lightness, and readability. The watch features a visually appealing fumé dial and a sandblasted 41mm case with polished accents, powered by the Miyota 9039 automatic movement. Some owners appreciate the "two-crown coolness" and the integrated slide rule bezel, calling it a "nerd watch" and a good Japanese-movement option under $1000. The canvas strap includes steel eyelets for durability, though one owner found the floating keeper caused discomfort. On balance, owners and reviewers rate the BOLDR Supply Co. Enigmath Sinharaja highly for its unique slide rule functionality and comfortable, attractive design at its price point.
