这个时钟是复刻的，轴采用2mm，建议发条盒厚度0.4或0.5，长度1.2m-1.5m

This clock is a replica, with an arbor diameter of 2mm. It is recommended to use a mainspring barrel thickness of either 0.4mm or 0.5mm, and a mainspring length between 1.2m and 1.5m.

看到作者沧桑的双手，感慨机械时钟应该传承更久远，深刻敬意

 Seeing the author's weathered hands, one can't help but feel that mechanical clocks should be passed down for much longer. 

Deep respect
