Langevin's paradox.

What is true is that, continuously, second after second, in Terrence's frame of reference, the internal mechanism of Stella's watch will beat less quickly. It is said that this one has a lesser internal chronotropy compared to Terrence's watch.

 Consider the following scenario:
 Terrence is inertial somewhere in space.
 Stella is in a rocket and is co-located with Terrence when
she starts her rocket engine and accelerates at 1 c/year
away from Terrence for 2.25 year on her clock.
Then she turns her rocket around and accelerates at 1 c/year
towards Terrence for 4.5 years.
Then she turns her rocket around and accelerates (brakes) at 1 c/year
away from Terrence for 2.25 years.
 When Stella is back at Terrence both stop their watches.
They are now co-located and stationary to each other.
Their clocks are side by side and can easily be compared.
Terrence clock shows 23.7 years.
Stella's watch shows 9 years.

Fortunately, we have GPS now, so we can be
absolutely sire this insane gedanken/fabricated
bullshit has nothing in common with real clocks,
real observers or real anything.
