Watch goes slow when wearing. watch goes slow when wearing it but keeps time when not wearing

Question

watch goes slow when wearing it but keeps time when not wearing itBecause I started having a problem with an old reliable Acqua quartz analog watch running slow,  I replaced it with a new Timex quartz analog.  From the outset, that loses 2.5 hours a day on my wrist, but keeps time perfectly when not being worn.  No watch has previously exhibited this behavior on me.
