I'm psyched to get this back from my watchmaker this week. I've had it for about 5 years, and this is its first service while in my possession...still running at +3 sec/day, but apparently the gaskets in the crown had deteriorated, so setting it was increasingly difficult, and I thought it was about time for a full service in any case. The 16750 was an interesting transitional sports watch from the early '80s -- still with acrylic crystal and matte dial (originally), but with a higher-beat cal. 3075 having a quick-set date mechanism (finally). I have mine on a Jubilee, but an Oyster bracelet was the most common combination for this model (and its 1675 predecessor).
