Based on the number, it is thought that this chronometer was made around 1882.
The micrometric balance, or as it was marketed, the 'Double Compound Micrometric Equation balance', uses cone shaped weights and three central strips of metal to account for temperature error, including middle temperature error. There is also a collar of brass that partially surrounds the balance, the idea being that, should the fusee chain break, the escapement would still be protected. The escapement was commended when it was introduced around 1862, as allowing the owner to adjust the chronometer's rate without needing to remove the balance.
