I took my Mathey-Tissot Quartz Watch and filled it with 100% Silicone Oil with a viscosity of 50. I found the oil on ebay(search the brand label seen in the video). The overall project took about 15 minutes. It was extremely easy and came out wonderful the first time. No bubbles in the case, no bubbles under the crystal near the dial, completely filled in again super easy.
