the big revelation about the Super SUB is the movement....... its made of wood..... na, just kidding. It is not the ETA 2824-2 that has been the mainstay of the Doxa SUBs for the last 5 years, it is the ETA 2892/A2.
Although the 2824 is a very robust and resilient movement, Doxa wanted to up its game and go with a "better" movement. As mentioned many times before the ETA 2824 is actually a progression from the ETA 2472 which is technology from the late 1950's. The 2892 was developed in the 1970's and if you read the review linked below you will see why it is the base movement of choice for the high end Swiss watchmakers such as Girard Pirregaux, IWC Flieger, the Omega Seamaster planet ocean and many others. Both the 2824 and 2892 are good movements but the alloys, the components, the final finishing used in the 2892 are superior in every way (according to ETA). The 2892 is made in a different plant with the best ETA watchmakers sitting there assembling them.
Here's the link. Have a read.
Guys when you put all the separate components together of the Super SUB, it really is an amazing package and at the returning customer price, its what your credit card was made for

The ETA 2892.A2 is however, widely considered the more upscale of the basic ETA movements, and it certainly a newer design dating to the 1970's where as the 2824 traces its roots back to the 1950's. The 2892 is fitted with top quality components. The 2892 is an automatic winding, twenty-one (21) jewel movement, available in three executions or grades: Elaborated, Top and Chronometer. They key components which differ at the line of demarcation between Elaborated and Top are the pallet stones, balance wheel & hairspring and the regulator mechanism. To illustrate the differences in accuracy garnered by the successive grades, consider the following specifications: the Elaborated grade is adjusted in four positions with an average rate of +/-5 seconds/day with a maximum daily variation of +/-20 seconds/day; while the Top grade is adjusted in five positions with an average rate of +/-4 seconds/day with a maximum daily variation of +/-15 seconds/day. The Chronometer grade must meet strict standards prescribed by the [COSC]: an average rate of -4/+6 with a maximum daily variation of +/-5 seconds/day. The wider range for the Chronometer grade is designed to take into account the differences in a watches rate between static positions, as when the tests are performed, and the dynamic positions as when a watch is actually worn. Chronometer grade movements are serial numbered. Moreover, the degree of decoration on the movement's parts, generally an aesthetic improvement, increases with the grade.
The 2892A2 is regarded by many horologists as being in the same 'quality' range (accuracy and reliability) as the in-house produced Rolex movements. Insofar as accuracy is concerned any movement which is expected to be COSC certified or is in fact COSC certified must meet the same standards. The ETA 2892.A2 is usually found in the more expensive and prestigious watches and brands. Owing to it's relatively slim height of 3.60mm, the 2892.A2 is a favorite of watch brands that market complicated movements such as Breitling with its trademark chronograph (stop watches). Given the slim dimensions of the 2892, it provides a good platform on which to add or build a chronograph complication.
