Ball Watch Engineer Master II Diver GMT; Faithful Diving Watch Utilizes Impressive Technology
Ball Watch Company is quickly becoming a perennial favorite of mine for their utilitarian designs and reasonable prices. Ball watches exhibit frequent feats of useful technology or features, but the Engineer Master II Diver GMT really hits a home run. It will be formally unveiled at Basel World 2008, but the key aspects to its anticipated success are its high legibility, use of tritium gas tubes, and DLC (Diamond-like coating) covered case.The design itself continues to be refined, and here reaches a new level of legibility.

Full overhauls seem unnecessary and I was thinking of going the partial maintenance route for some peace of mind.Has anybody here gotten a partial service from an Omega Service Center, and if so how was your experience/wait time? The cost is significantly lower than a full overhaul, naturally:Thanks! And here's my ragtag band of Seamasters:
