Rolex Bubbleback ref 2764 with subsidiary seconds from 1942

This is a vintage 1942 Rolex BubbleBack Oyster Perpetual Chronometer Men's Watch with a ref.2764. The watch features a subsidiary seconds and silver fixed bezel and a gray stainless steel case with a  caseback. The watch is equipped with a mechanical automatic movement and a two-piece leather strap.

This is my second attempt in getting the watch. The first time, I have placed a bid lower then US$1950+20 and I have failed to get it. For some strange reasons, the same watch was listed again on eBay but by another seller and I have managed to get it at a lower price US$1775+US$102.(HK$13,858)

I have collected a few Rolex Bubbleback but this is my second Rolex bubbleback in subsidiary seconds hands.
