Jaeger LeCoultre Master 148.8.31

The Master Tourbillon reference 148.8.31 represents Jaeger LeCoultre's approach to displaying the tourbillon complication within their Master collection. This reference distinguishes itself through its 42mm proportions and rose gold construction, positioning it as a substantial presence within the tourbillon offerings. The 42mm case is crafted from 18k rose gold and features a silver dial protected by sapphire crystal. A manual-winding movement powers the timepiece, requiring daily winding to maintain operation. The fixed bezel contributes to the clean case profile, while 50-meter water resistance provides basic protection against moisture exposure. This reference appeals to collectors seeking tourbillon complications in precious metal cases with larger proportions. The manual movement requires engagement from the wearer, distinguishing it from automatic alternatives within the same model range. The rose gold case material and 42mm sizing create a notable wrist presence for those preferring substantial timepieces within the Master Tourbillon series.
