Due to some major changes in the movement supply chain in Switzerland, many quality independent watchmaking firms are now using Sellita watch movements for their mechanical watches. At first glance, Sellita watch movements can be mistaken for those from another watch movement manufacturer. If you see the trade mark SW as shown in the photo, you have a movement from Sellita and, if it needs spare parts, you need to call us for genuine Sellita material. We can supply every part for the Sellita movements you will be called upon to repair. Please note that because Sellita movements can be repaired, they do not supply complete movements to the trade. You can restore these quality movements while you utilize your watchmaking skills.
