A Legacy Machine LM2 in Titanium. The LM2 is MB&F’s approach to the dual balance problem, utilizing two independent ‘flying’ balances coupled to a differential wheel visible at 6 on the dial, which averages the result from both escapements to one final gear train. It features an engraved teal dial, traditional hand finishing techniques by Kari Voutilainen, and grade 5 titanium case. This is nº 4 of just 18 examples ever created, the most dramatic expression of dual balance, differential timekeeping architecture yet designed.
