This extraordinary 1926 Hamilton Square represents a masterpiece of American watchmaking of the era. The 14K white gold case encloses a particularly luminous dial, a distinctive feature of models in this series.
The 986A movement, equipped with 17 jewels and a 6/0 caliber, guarantees the reliability that distinguishes Hamilton mechanisms of this generation. What makes this example particularly interesting is its transition to the 987 movement, introduced in 1927 with the addition of the second hand.
The dimensional differences between these two calibers necessitated the creation of dedicated cases, giving the 1926 and 1927 Square models a unique construction.
During the same period, Hamilton expanded its collection with the "geometric" Barrel model in 1927 and the Tonneau shape in 1928, consolidating its position in the international watch market.

The Square remained in production until 1930, available in both men's and women's versions. Noteworthy is the absence of a sub-dial for the second hand in the 986A movement, an element that gives this watch a particular charm, a testament to uncompromising functional elegance. Dimensions: 35 x 28 mm.
