Hands-On With Smooth Leather Straps IWC Portugieser Constant-Force Tourbillon Fake Watches

The compact and cleverly designed IWC tourbillon with integrated constant force returns.

Although featuring a constant force tourbillon, moon phase and a four-day power reserve, the best-selling silver Arabic numerals replica IWC Portugieser Constant-Force Tourbillon watch is a dialled down version of the most complicated (and expensive) IWC wristwatch ever made, the Portuguese Sidérale Scafusia introduced in 2011.

Powered by the same calibre 94800 found in the discontinued Ingenieur with the same features, the durable copy IWC Portugieser Constant-Force Tourbillon has an aperture at nine o’clock that reveals the centrepiece of the movement, a large tourbillon regulator.

Though the tourbillon itself is large, the cage measures almost the radius of the dial and the balance wheel is only slightly smaller, the construction is compact, with the constant force mechanism integrated into the tourbillon.

Stainless Steel Cases IWC Portugieser Constant-Force Tourbillon Replica Watches

Developed in collaboration with complications developer Chronode – founder Jean-Francois Mojon worked at IWC for a decade before starting Chronode – the tourbillon has a tiny spring mounted under the escape wheel.

Once a second this spring accumulates and releases power from the mainspring, ensuring that the escapement is driven by a small, steady supply of energy. This in turn keep the balance beating at a constant amplitude, and also gives the tourbillon cage a rotation that moves in one-second steps.

That only holds for the first two days of the 96-hour power reserve, when the mainspring is sufficiently wound to provide enough power to keep the constant force mechanism going at an optimal rate. Once the two-day mark is passed, the constant force disengages and the tourbillon functions like a conventional tourbillon.

At one o’clock is the double hemisphere moon phase, with the moon phase disc cast to resemble the cratered surface of the Moon. And just below that is the power reserve display.

Unlike the Portuguese Sidérale Scafusia that incorporated a star chart on the back of the watch, which is why it is an enormous 17.5mm in height, the Swiss 46mm copy IWC Portugieser Constant-Force Tourbillon is a relatively slim 13mm, even with the high domed sapphire crystal.

The case is a large 46mm, which gives it relatively elegant proportions though it is still a large watch.

The back reveals the movement and its workmanlike finish. Historically IWC has never been associated with decorative finishing – clever and concise engineering was its thing – so the functional appearance of the movement is in keeping with the brand’s identity.

Even if not fancy the movement is attractive, with variation of the surfaces finishes that create an appealing contrast. The overall finishing is careful, albeit applied by machine.

That being said, the styling of the movement, which is reminiscent of an automobile engine, doesn’t quite suit the classical design on the front. And that explanation for that is likely that the calibre 94800 was originally designed for the Ingenieur Constant-Force Tourbillon, a high octane-high complication.

The modern fake IWC Portugieser Constant-Force Tourbillon is customisable, with the client able to mix and match for the case, dial and strap. The case is available in red gold or platinum, with the choice of four metallic finish dial colours, as well as a wide range of straps. Further customisation beyond the options offered is possible, but likely at significant additional cost.

The prototype of the sturdy copy IWC Portugieser Constant-Force Tourbillon is in stainless steel, which unfortunately is not an option for the watch. The lightness of the steel case makes it more wearable than the precious metal versions.

Price and availability 

The Portugieser Constant-Force Tourbillon (ref. IW5901) is made to order, priced at S$325,000 in red gold and S$360,000 in platinum. Those are equivalent to US$230,000 and US$260,000 respectively.

Hands-On With The Fake IWC Da Vinci Laureus Chronograph Watches With Blue Dials Online

The simplest chronograph in the new Da Vinci collection also happens to be a limited edition.

The redesigned IWC Da Vinci collection introduced earlier this year leaned towards big ticket complications and entry-level models, but not much in-between, except for the Da Vinci Chronograph “Laureus Sport for Good Foundation”. Steel and equipped with a proprietary movement, the Arabic numeral copy  IWC Da Vinci Laureus Chronograph watch sales is the sort of reasonably accessible (with a bit of saving) wristwatch that IWC does well.

The Da Vinci Laureus the latest in an annual series of limited editions conceived to raise funds for the eponymous charity that brings sport to disadvantaged youth. This is the 11th in the series and more expensive than the average Laureus edition because of the proprietary calibre 89361 inside.

At 42mm in diameter and 14.5mm high, the Swiss steel case  replica IWC Da Vinci Laureus is a largish watch, on the verge of being too big but not quite. It’s helped by the articulated lugs, which allow it to feel smaller on the wrist, though there is no escaping the height of the case.

One reason for the height is the domed sapphire crystal, a touch that’s meant to invoke vintage watches. The onion-shaped crown is probably meant to do the same, and it suits the overall design. Both chronograph pushers also have onion-shaped rings at their base, presumably to match the shape of the crown. But the buttons are not screw-down pushers, making the rings perhaps unnecessary aesthetic additions.

The case is entirely polished, front, back and even the lugs, which is less interesting than having alternating brushed and mirror finished surfaces. The rationale for this finish is likely the design inspiration for today’s Da Vinci: its namesake of 1985 that was similarly shaped and also entirely polished (save for uncommon examples in steel that were entirely brushed).

While every year’s Laureus edition is different, all share the same dark blue dial. Varying from a dark to medium blue depending on the light, the dial has a metallic finish that’s easy to like.

Finished with a radial brushing, it has applied numerals, white printing and red accents. Up close, several details stand out. The chapter ring carrying the minute track has a circular grained finish, serving to frame the central portion of the dial. Both chronograph registers have a stamped concentric pattern (or azurage), which is standard for chronograph watches but give the dial texture. And both chronograph sub-dials are also ringed by a metallic border, an element that echoes the hands and numerals.

Positioned at the quarters of the dial, the red accents don’t appear to serve any functional purpose, which can be annoying for a nitpicker, but they make for a pleasing colour palette.

Notably, the numerals on the dial are all of a serif font specific to the IWC Da Vinci fake watch with black strap, right down to the date disc. It evolved from the custom font created specially for the previous generation Da Vinci, which had significant attention put into its conception but nonetheless ended up a chunky, tonneau-shaped watch that did not sell well. Fortunately the new Da Vinci sticks to a tried and tested shape, while preserving the unusual font that’s a mix of classical and contemporary.

Being white, the date disc is jarring against the blue dial with a somewhat odd position – a consequence of the movement size relative to the case – but at least preserves the symmetry of the dial.

In the tradition of the Laureus watches, the solid back is decorated with an etched reproduction of a child’s drawing. Every year the Laureus foundation – which has both IWC and Mercedes-Benz as sponsors – runs a contest to select a drawing for the following year’s limited edition wristwatch. Last year’s content was won by Hou Ye, a 12-year old from Shanghai who’s a Paralympian at the Special Olympics East Asia. Ye’s winning entry is a self portrait showing him on skis.

Underneath the back is the calibre 89361, part of the 89000-calibre family of movements. Positioned as IWC’s upper-end chronograph movement, the calibre 89361 has a solid list of features.

That includes all the bells and whistles expected in a mid- to high-end chronograph movement, namely a vertical clutch, column wheel, and also a useful 68-hour power reserve. Additionally, it has a flyback function, as well as the hour and minute counters being co-axial on the register at 12 o’clock, explaining the relatively clean dial. Also worth mentioning are the free-sprung balance as well as IWC’s own Pellaton winding mechanism.

The movement is the primary reason this costs what it does. In contrast, IWC’s entry-level chronograph movement, which is based on the economical Valjoux 7750, is found in the new Ingenieur and that costs a third less than the Da Vinci.

That being said, it’s probable that IWC will introduce a cheap replica IWC Da Vinci chronograph in the regular collection in the near future (think steel case paired with a silver or grey dial), which will cost less than the Laureus limited edition.

Price and availability 

The Da Vinci Chronograph “Laureus Sport for Good Foundation” (ref. IW393402) carries a price tag of US$12,700 or S$19,100. It is already available at IWC boutiques and will reach authorised retailers soon.

Ladies Watches Of The Week: Fake IWC Da Vinci Automatic Moonphase Watches

With the introduction of the new Da Vinci Perpetual Calendar, IWC also revised the Da Vinci line-up for ladies. While this may surprise some, the women’s models always had an unyielding position in the Da Vinci-line up, a tradition that IWC continues now with the automatic moon phase ladies model.


One of the earlier Da Vinci models for women was also featured a moon phase. It was powered by a so-called mecca-quartz movement, which consists out of a quartz movement, but with a mechanical chronograph and moon phase indicator. For their latest copy IWC watch with Arabic numerals forgo not only the chronograph function but also the battery needed to power it.

IWC Da Vinci Fake Watches With Diamond Bezels

Instead, they fitted it with Caliber 35800, and automatic movement, with a 42-hour power reserve and a moon phase complication at 12 o’clock. With a moon phase, the number of teeth on the mechanism determines the precision. IWC fitted the one in the Da Vinci with 59, which means that you have to adjust it one day in about every two years, seven and a half months.


Next, to the moon phase, two other things stand out with the Da Vinci. First, there is the perfect size of 36mm. This ensures that the replica watch with top Swiss movement retains its feminine elegance, yet at the same time has quite a presence on the wrist without being uncomfortable large. Comfort and wrist presence are also ensured by the movable lugs, a trademark of the very first Da Vinci. Between those lugs is an alligator strap fitted, made by Santoni, and featuring stunning brown color tones. IWC designed to make the Da Vinci 36 Automatic Moon Phase a watch for every day. They not only succeed in this by making the watch comfortable and practical but by also making it beautiful they turned this from an option into a desire.
