This is a really good dial indicator. Very durable and made to high Japanese standards. It comes with a calibration certificate. The difference between this all-silver version and the blue-rimmed version sold everywhere is twofold. It's not just about looks. The silver version is the old model and the blue bezel is the newest model, but most importantly the old model has a 2 3/16 inch dial diameter and not the 2 inch of the newest model. Both have the same quality characteristics. I actually wanted the old model because of the larger face diameter.
