Early in the film we find Lovell link sitting with his wife in their link backyard after the ArmstrongAldrin moon landing. They're laying on lawn chairs staring up at the link Moon imagining the crew looking back up at Earth. As Lovell ponders the impossible made possible enjoying the evening with his wife we can see the Speedmaster affixed to his wrist 000659. If only he and the watch knew what lay ahead.

The primary issue the chronograph as a mechanical instrument has always faced is link related to the effective and efficient link transfer of energy. Since chronographs aren't constantly running they can end up consuming quite a lot of power when physically actuated causing link a negative impact on the movement's amplitude. And if you have two chronographs positioned in a single movement like on the LM Sequential the detrimental effect would naturally double.
