PURPOSE:To simplify a waterproof structure to an IR LED and to improve operability. CONSTITUTION:The IR LED 11 for data transmission is disposed on the dial surface in the watch. The optical axis direction of the IR LED 11 for data transmission is inclined with the direction perpendicular to the dial of the watch. Further, a lens part 12a for correcting the light output pattern of the IR LED for data transmission is formed on dial protective glass 12. |
