Since Timezone takes the hands-on approach to horology, I thought the SF might provide the simple, quick-and-dirty answer. I recently picked up 2 timepieces, that, interesting, both use the ETA 2892 as the base movement. The modified 2892 is running about 5s fast/day which is acceptable in my books--it was also purchased used. My "new" watch is a discontinued model, brand new, that has been sitting on the shelf for around three years. Its running b/w 15-18 sec fast/day depending if I wear it or leave it on the dresser face up. So here's my question--is the second watch worth taking to the jeweler's and getting it regulated? How much would this cost (a relatively easy procedure)? Has anyone had any experience with regulating a watch in the past? And is there really a "burn-in" period, or is that another wive's tale? cheers, NCT Now, aren't you glad that you bought quartz?
