Top 10 Introducing the Audemars Piguet Royal Oak Offshore Tourbillon Chronograph 25th Anniversary Replica Watches Young Professional

Here we could see that IWC has gone with a traditional high-end Swiss watchmaking approach. While the simple fact that it employs a varying inertia free sprung balance is unchanged from its Cal. 50000 predecessor, the rate is, which has climbed to some more normal 28,800 BPH. IWC is a very interesting company since it is one of just a small few that produces several current-generation movements with free sprung or regulated balances.Looking near the balance wheel allows me to highlight the screws at the rim for you. These are utilized for both adjusting the poise and rate of this balance wheel, allowing it to do away with a need for a ruler. While ultimately more stable, it is also more difficult to correct, and variable inertia balances are almost always associated with upper-price range watches like Patek, JLC, Rolex and Omega, though there are recent exceptions in Damasko and Tudor, as an example. This specific iteration is among the oldest and most traditional of these designs, with screws on the outer rim of this equilibrium. Rolex, by comparison, uses a similar approach, but on the interior of the equilibrium. JLC frequently uses the same approach as IWC does here, as does Tudor in its own new movements.Getting really close now permits us to see an even sexier layout, the Breguet overcoil. Now this layout is seldom used outside of Rolex and Breguet, in which it’s used to boost the stability of the movement.One of the most significant changes in the Cal. 50000 is the use of dual mainsprings to reach its amazing 7 day power reserve. This was probably a decision designed to boost stability and multiple-mainspring layouts are becoming much more prevalent today.

Just six months after IWC revived the Portugieser Chronograph split-seconds with the Milan boutique edition in red gold, the watchmaker has introduced two more limited editions for its stores in Munich and Paris but this time in stainless steel.

The Portugieser Chronograph Rattrapante ref. 3712 (pictured above) was first introduced in 1995 – with the split-seconds mechanism invented by Richard Habring – and discontinued a decade later. And now a decade on it’s back, again.

That definitely means the hand-wound Portugieser Chronograph Rattrapante has found a favourable reception, and it’s not hard to see why. Simple but distinctively styled, the split-seconds version of the Portugieser chronograph has the advantage of not only an extra complication but it is also slim.

At 12.3mm high, the case is exactly the same size as the basic Portugieser Chronograph that’s automatic but lacks a split-seconds function. That’s because the split-seconds module takes the place of the self-winding mechanism, keeping the case height exactly the same.

There are two new additions to the line, both identical – stainless steel and 40.9mm in diameter – except for the dial colour and case back decoration.

The first is the Portugieser Chronograph Rattrapante Edition “Boutique Rue de la Paix” (Ref. IW371216), named after the luxury shopping street in Paris. This has a dark grey dial and black sub-dials, with an engraving of the Vendôme Column, the bronze-covered tower in the middle of the Place Vendôme, the famous square at one end of Rue de la Paix.

The second is the Portugieser Chronograph Rattrapante Edition “Boutique Munich” (Ref. IW371217). A dark metallic blue dial with red chronograph hands gives this more contrast, while the back is engraved with the Frauenkirche, the landmark cathedral in the centre of the German city.
