A great look at regulating mechanicals by ARA Master Watchmakers, creators of the Famous Silicone Strap (TM) (R) (C) etc.
Before we send a watch to a customer, we make sure it is properly regulated. Below, we will show how we regulate an eta 2824-2 movement which is found in our ARA dive watches. A watch should be regulated in three important positions: Crown Down, Dial Up and 12’Oclock Down. The fact that the eta 2824-2 has a very high beat, the accuracy can be guaranteed if regulated closely in these three positions. The higher the beat, the more accurate a watch is so it is not necessary to regulate in any more positions.
