<p>PROBLEM TO BE SOLVED: To provide a radiowave correction timepiece and a code determination method therefor, which are capable of reducing erroneous determination of a code.SOLUTION: A radiowave correction timepiece 1 includes: signal detection means 14A for detecting all of first level signals having a first-level signal width from among reception signals received within a given period from sampling-start timing; determination timing setup means 14B for calculating a total signal widths produced by adding all signal widths of the first-level signals detected by the signal detection means 14A, calculating timing during the given period, the timing of which a signal width of the first-level signal detected by the signal detection means 14A prior to the timing is a half of the total signal widths, and setting the calculated timing as determination timing; elapse time detection means 14C for detecting elapsed time from the sampling-start timing to the determination timing; and code determination means 15 for determining a code on the basis of the elapsed time detected by the elapse time detection means 14C.</p> |
