Jewels dont equate to quality.
The Ball Trainmaster first flight actually uses a modified ETA 2892.A2 movement which is an exceptionally good ETA movement.
In fact the Omega coaxial movement used in the Seamaster is based on this movement and re-branded as the Omega 1120 for the Seamaster Professional 300.
Jewel count means little relative to the quality of the movement. The jewels are relatively inexpensive and are used as bearings to reduce friction. They are only used where needed... It's not like we're counting diamonds in a necklace or engagement ring. As for this particular movement, it's an ETA that can be found in watches of all pricepoints... from Hamilton to Sinn to Tudor to Panerai and everything in between.
You've correctly stated that much of the cost IS related to the name and the looks, but also the quality of everything else in the watch. The Panerai 57 is a $6k+ watch, the Tudor Heritage Chrono Blue is a $3.5k watch, the Longines Lindbergh Hour Angle is a $2.5k watch, the Hamilton Intra-matic is a $700 watch and the Hamilton Jazzmaster is sub $500. What do they all have in common? The ETA 2892.A2 mvmt.
You have to get to much higher pricepoints before the movement becomes a significant cost component (ie., think the highly decorated in-house movements... typically found in watches 10k and above).
MRichIf a watch and its moving parts requires x amount of jewels for y number of parts, having x + 5 jewels for the same y of parts doesn't improve the watch.
