Miyota
Miyota's no-date variant of the 9015 platform, eliminating the date complication for a cleaner dial design. At 4.0mm thick it is notably slimmer than the 9015, making it attractive for watches where case thickness matters. The absence of a date mechanism also means one fewer point of mechanical complexity, and many watchmakers consider it the most refined movement in Miyota's lineup.

Owners talk.
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.
