An old pocket watch

It does not have anywhere near $2800 in gold. It appears to be swiss and would date to the 1880s or 1890s most likely. Would need to see the watch movement itself to determine origins for sure and possibly identify a maker. If the watch is 2" diameter across the face not including the stem/winding crown, I'm guessing it weighs about 75-80 grams,  most swiss pocket watches use very thin gold and are on the light side. Yours does appear to have a nice solid gold dial. You can expect there to be 20-30% of the weight in gold if that with open faced watches of swiss nature. With those numbers in mind, you're looking at about $600-$925 or so in actual gold weight assuming it is 18k gold like comprabale watches usually are. These watches values are a direct reflection of high gold prices and the their solid gold cases, there will be very little premium over the gold content value for the watch itself as it appears to be a very mid class timepiece, it looks nice but in reality they were mass produced and the internal mechanism is very common, the same watch 5 years ago would have been selling for $300 or so. Add another $50 or so for the movement and that's what I would expect  market value to be if you were to put it up for auction tomorrow. It has a very small chance of being English as well, but after seeing hundreds of similar watches I am almost certain the movement will be unsigned and the watch is swiss. Obviously if the chain (watch fob) is solid gold that would add some more value, but at least from the photos given the colorization points to it being gold filled and worth $30-$50 or so. If it is solid gold it would be a low 9k or 10k purity and an estimate on value would be $200-$300. Thanks for sharing, I love looking at pocket watches. Again, if you ever get the back of the case popped off (I would reccomend taking it to a watch maker or jeweler for doing such to avoid damage) feel free to post a picture or two of the movement.
