There is likely to be break in period. Often a watch will slow down a few seconds during that period.

Have you been wearing the watch 24/7. If not, performance can be strongly affected by the position you leave the watch in at night (due to gravity and friction).

Wear it full time for a few days to get a sense of the actual accuracy then find an over night position that compensates for that inaccuracy

The performance of mechanical watches is subject to movement and gravity. In different positions, the performance can and will differ. With good, well regulated, watche movements the differences between the 6 standard COSC postions will be small. COSC standards are +6 to -4 seconds/day.

While there are six general positions, there are also an infinite number of other positions that can affect performance. Each can and ususally will yield slightly different results.

1. Crown right (like a clock on the wall.
2. Crown left (like an upside down clock on the wall
3. Face up (laying on its back)
4. Face down (laying on the crystal)
5. Crown up (like a clock on the wall with the 3 o'clock position where the 12 should be.
6. Crown down (like a clock on the wall with the 9 o'clock position where the 12 should be.

My SMP run around 2 seconds fast per day when I wear it 24/7. Through experimenting I found it runs around -5 seconds a day in the the crown right position. When I normally wear my watch around 16 hours per day, it gains around 1.5 seconds. When I place it crown right over night for around 8 hours, it loses approx. 1.5 seconds. The result of this practice is my SMP was last set 2 months ago and it is currently less than 2 seconds off

When you wear your watch 24/7, the results you'll see is more or less the average of all the positional differences since your arm is constantly shifting position during the day and even at night. If you were to monitor the results in each of the various positions I mentioned above (usually for 24 hours with the watch fully wound) you might see differences between some positions of a few seconds or more.

: I have now owned my smp auto for 2 weeks and
: have logged a consistant time gain of 5
: seconds per 24 hours.(as per. to the
: official time clock website)Is this
: something I could have corrected with an
: adjustment?Should I wait longer because of
: the break in period?Thanks in advance for
: your responces.
