For under the price of an entry Rolex sport model you get a ceramic bezel and dial, a METAS certified movement that shrugs off 15,000 gauss, a display caseback and 300 m of water resistance. Its finishing and spec sheet are a step above Tudor at this money, and owners routinely report it running within two seconds a day. It is the modern dive watch here, made to be worn hard, in water, and still look sharp with a shirt.
It packs the most technology in this tier: ceramic dial and bezel, METAS certification and a helium valve.

What owners say
On WatchUSeek and Omega Forums owners praise the accuracy of the 8800, with many logging 0 to +2 seconds a day, and the durability of the ceramic bezel. The most repeated complaint is bracelet weight and wrist fatigue, often solved with the OEM rubber strap; the helium valve and date window are frequent talking points.
