Beautiful 16s Waltham 21j "Crescent Street" wind indicator

A lovely Waltham 21jewel Crescent Street Railroad watch with wind indicator, or power reserve indicator.
This 16 size model 1908 was made in 1915 and is running perfectly whilst keeping excellent time. The wind indicator is working as intended. The movement is very high quality featuring a semi capped Swiss lever escapement with double roller, Sapphire pallets, gold timing screws and a micro-regulator. There are also gold jewel settings, a gold (alloy) centre wheel, and a jewelled barrel arbor.
To comply with railroad specs the watch is stem wind and lever set, both functions working smoothly.
The movement is held within a 20 year gold filled case with hinged front and rear covers and a hinged internal dust cover. All of the hinges are good and all covers open and close as they should. The case exhibits hardly any wear as all of the gold is bright and lustrous.
The white enamel dial is in super fine condition as I can find no flaws. Good set of hands under a very good mineral crystal.
