I bought a Rolex Explorer back in B.C. days (before children). It started losing minutes per day so I have set it aside until I can get it maintained (yes, about $750 so it may be a a while). In the interim (however long that may be) I have found the automatics at CountyComm to be very satisfactory. The "superluminova C3" (I had to look this stuff up) is exceptionally bright with only minimal sun (or flashlight) time. Frankly I don't have a lot of operational need for tritium. The watch has proven to be very durable and I am very fond of the clean dial. It has proven water resistant and accurate (ca. +/- 30 sec per day . I have the Maratac Pilot original (with the triangle at the 12 o'clock position). Usual disclaimer, not affiliated etc. Just sharing my experience.
