Are you 100% certain that the watch is fully wound when you begin your check of its power reserve? In other words, have you wound it enough so that you can hear a faint clicking noise as you wind (which is the overwind protection mechanism engaging)? If not, you might want to try another test.

Also, how old is the watch? A watch will typically slow down and start to keep poor time when it is in need of servicing (usually every 4-5 years). On the other hand, if your watch is still under warranty, you could have it adjusted by Omega free of charge.

35-36 hours is a bit on the low side, but not low enough that I would be concerned as long as the watch is keeping good time. Omega has flip-flopped on their stated power reserve for the 1120 movement (at one time it was 42 hours, now their website says 44 hours). Also, a watch will typically start to keep erratic time as it approaches the end of its power reserve. If you are getting 35-36 hours of perfect timekeeping, I wouldn't worry.

When you do send the watch in for its regular servicing, you can mention the slightly low power reserve in your letter and ask for it to be corrected.
