What does a main spring do?

How long does a mainspring last?
The mainspring in the common 1-day movement is calculated to enable the watch to run for 36 to 40 hours, i.e. 24 hours between daily windings with a power-reserve of 12 to 16 hours, in case the owner is late winding the watch. This is the normal standard for hand-wound as well as self-winding watches.
How do you size a clock mainspring?
Measuring is done to get the size of the new mainspring to match up to the old one. Measure the width first, then measure the thickness with a micrometer. Then the final measurement is the approximate length. Take all those numbers and compare them to the chart.
Where is the retaining pin on a colt officer spec mainspring housing?
The retaining pin hole looks like it would be correct for a Colt Officer spec mainspring housing. It appears to intersect the rail on the side of the housing as it should. Officer mainspring housings will typically have the hole in the same position as that S&A part.
Should I elongate the detent hole on my mainspring housing?
Elongating the hole may allow the detent to project too far down and cause very difficult mainspring housing pin removal. I’d recommend contacting Fusion and asking them for a replacement. Brownell’s will refund no questions asked, but Fusion may replace it.

Note that the holes do not intersect the rail and rail slot, but are spaced a few thousandths away from the rail and rail slot (the rail on the housing and rail slot in the frame).
