ELGIN 14k Innocence Double Hunter Case Pocket Watch

This is a double hunter case pocket watch from ELGIN with beautiful engraving.
It is a box hinge type, suggesting it was a high-end model.
The crown turns, and the second hand moves intermittently. When the second hand is moving, the minute hand appears to move. The watch has not been serviced (OH), so please be aware of this before purchasing.
I received this from an acquaintance. I am not an expert, so I may not be able to answer all questions.
Case diameter: 3.8 cm
Including crown: 5.5 cm
Thickness: 1.3 cm

The following information was researched by AI:
The serial number on the Elgin movement side, 246914〇, indicates it was manufactured around 1885 according to Elgin's manufacturing number table.
On the other hand, the Keystone case serial number 18681〇 corresponds to a case made around the early 1880s (circa 1880-1885). The periods of both align closely. Therefore, it is reasonable to estimate that this Elgin 14k double box pocket watch was completed and assembled around 1885 (approximately 1883-1886).

The weight is 56g as shown in the photo. The case and hinges are solid with no play. The mechanical side cover is double, and the first owner's name is engraved on the dust cover.
(This is not shown in the photos as it allows for individual identification, similar to the serial number.)
With the soaring price of gold, the circulation of such pieces has significantly decreased. Furthermore, it is unlikely that such items will be newly manufactured at a realistic price.
