Just found this site, blog of a watchmaker frm down under.
You would be surprised at how some ppl wear their watches and the damage that comes with it.
Spent the last hr going through his older entries and its a very interesting read.
2 important things i learned from the site.
- Even a NOS mechanical watch, its best to overhaul it (if its worth to do so, not really for a rm300 seiko5 IMO) as disassembling the watch reveals alot of dirt n dried up gunk.
- When you drop and crack your cystal, pull out the crown n stop the watch.
