hmt Tarun Handwind (Citizen Licensed Caliber) 17 Jewels
This is the Tarun Model that I am wearing
however NOT in humid conditions. I found this nice flex band matching the 17 mm lug width at my local watch parts shop quite a few years ago. A perfect match in my opinion. Flex bands can underline the vintage character of a watch. While the gap between the straight end-link and the case is not normally appreciated, it can enhance "grandfather's looks".
