Notes

This watch is part of a limited edition of 50 examples, made in 1992 to commemorate the 50th anniversary of the cal. 27 chronograph, ancestor of the cal. 321 and 867 which equipped, now, the Moon Watch.The skeleton movement was entirely hand-made by Armin Strom, first cut, then individually chased, brushed and champfered, the head of the screws polished one by one.
