In January, we blogged about an article that Henrik Korpela, the director of K&H Watchmaking Competence Center, wrote exclusively for Watches by SJX. The subject of that article was a thorough step-by-step explanation how to flat polish a screw head, bevel the slot and round polish the thread end. If you missed it, here's the link.
Henrik wrote another article for Watches by SJX that was published a few days ago. This time it's about bluing (or tempering) and is an extremely interesting subject. If you are into fine watchmaking and want to know a little bit how things are done the 'hand made' way, why don't you take a look? We promise it's worth it.
