The 103T wears this nice nickname due to the specific satellites cross. The 103T is not a "classic" 103 with a new saphire. The way the satellites move is changed: they move simultaneously doing a 480 degrees rotation. When you turn the crown, you can see the ballet of the 4 satellites: a very impressive visual effect.
The cross is not the same: it looks like Tarantula feet covering the satellites. In order to avoid confusion, only a part of them is visible. The material used for the cross is no longer titanum but dark ARCAP, a copper/nickel alloy.
The caliber used has the same basis than the classic 103: the reliable Peseux 7001.
The case is made of stainless steel treated with AlTiN (Aluminium, Titanium, Nitride).
This watch is another masterpiece from Urwerk. It may look similar to other 103 at the beginning but once you wear it, you feel the difference.
