SHORT BRAND HISTORY. IWC is one of the oldest watch company with aviation and military heritage, which obviously drive people crazy about it, even there is a real chase for it. Starting in 1868, a qualified Swiss watchmakers named Florentine Ariosto Jones, who was American, founded International Watch Company in Schaffhausen, which in short is what we refer as IWC nowadays.

Among all watch productions, IWC is certainly one of the most earth-concious company, by uses only 100% renewable energy since the start, recycles waste heat and rainwater. Hat down for starting it early even before Greenhouse effect is booming.

First things first, Pilot watch, as it is labelled, from IWC engineered for aviators.

I always wonder why this particular model of Big Pilot series called Transitional Dial? It is the old movement, encased in a new diameter of 46mm, with first ever Probus Scafusia onion-like shape crown. Having said that, this IWC 5002 is indeed the 1st generation of Big Pilot, while adopted the vintage yet modernized military look. This IWC model has B-Uhren inspired models (photos: B-uhren models), 1940’s pilot watch model, judging from the slightly thick but still comfortable to the wearer, housed Anti Magnetic Shielding.

Onion shaped crown that is ergonomically comfortable for wearer to adjust time and date without needing to ‘dig’ it, and scratch the case with your nails, well thought of indeed.

Black charcoal-like surface dial make it easier to read the time and date in almost all kind of situation, day or night.

The signature Triangle logo.

Calibre 5011 Movement.

For sure you would like to know whether this watch is Collectable? I can surely says that this watch is extremely collectable, due to its low production number, short production year, military elegancy look, while embracing the historical movement in a modern case.

Unveiling 1st September

Hello WBians, we are so excited to announce that we’ve found out from Rolex, they will be releasing new model, new catalogue out of timeline. We all thought that Rolex has given up on 2020 models and just pushed it to 2021, and yet they surprise us with early Christmas gift with announcing the teaser about their release in September.

WHY do Rolex release new watches?

No one truly knows why, except the folks in Rolex. It makes sense however if we go back to history. Rolex had always released new models during Baselworld which is around March/April of every year. This means that Rolex’s new models were designed before the Baselworld. Research, testing and production for the shifting to new models should take around 3 to 4 months before Baselworld.

Rolex had a long end-of-year holiday that limit their production capacity. So our best guess is, Rolex has been ready for the release since early of 2020. Unfortunately, Covid-19 became a world-wide pandemy, and Baselworld got cancelled. Prolonged pandemic situation all over the world surprisingly DID NOT decrease the demand of Rolex watches. We, as watch traders and enthusiasts, have proved this evidently by seeing how Rolex watch sales remain the same despite of the large-scale Social Restrictions (PSBB, as what we call it in Indonesia).

Being the market leader of Swiss Made luxury watch, they decided to surprise us all with the unveiling of new Rolex watches in September 2020. This hopefully means that production resumes, and we hope that the prices will be more stable.


What new watch will Rolex release this year?

Our guess is either Submariner or Air King because these watches do not yet have the reference starting with 12……, as most recent releases of Rolex watches. Having the reference numbers start with 12 means these watches are equipped with new Rolex engine or movement.

Peeking at Rolex's YouTube teaser, which is making us even more anxious, we see some elements of water, with some sort of sea foam like animation. We saw a bit of ocean theme going on, so our best guess is they will be releasing some diving-related watch this time, and it is the submariner. Now the real question is, HOW will they change its signature Submariner look?

The new Submariners will have a slightly bigger diameter of 41mm (40mm is the previous diameter).

The watch positioned second from the left is interesting, because it has a green bezel and a black dial, previously seen in the famous "Kermit" submariner (circulated around 2004 - 2010). The third watch is a white gold watch, with blue bezel and black dial, which will presumably replace the blue bezel and blue dial submariner nicknamed the "Smurf".

Additional, yet very important sidenote:

Along with the new guarantee cards that they will issue for the new watches, it will be a nice touch by Rolex for (end of) 2020.

Thanks for reading.

On Today’s blog, we will write about one of the most popular Rolex model, which is the GMT-Master. The Rolex GMT Master has always been a popular watch since its debut in 1954. Many people nowadays called it Rolex Pepsi. Whenever people talked about Rolex Pepsi, the watch they are referring to is the Rolex GMT Master.

What is a Rolex Pepsi?

The first ever Rolex GMT-MASTER watch uses two colors for its bezel; blue and red. The red color denotes the day time, and the blue denotes the night time. The first Rolex GMT-Master bezel uses the bakelite material. A more familiar term which explains bakelite is plastic; it is the world’s first synthetic plastic. This combination of colors closely resemble the popular drink Pepsi, and thus it is famously called “Pepsi”.

Aviation watch

The Rolex GMT Master was initially developed in cooperation with Pan Am, who is one of the largest airline company at the time. In the 1940s and 50s, flying distances got longer and thus pilots travelled through multiple time zones. The pilots and the flight attendants faced a new problem, the jet-lag. Many studies showed that one way to fight the confusion caused by jet-lag was to have an instrument that could simultaneously display the home-time and the destination-time. Pan Am asked Rolex to develop a watch which could tell different times simultaneously.

The challenge Rolex face was to create a movement that is able to display 2 different time zones. The indication of the second time zone was achieved by an auxiliary hand with arrow-end and red-painted body, that rotates in 24 hours. To read the second time zone, it was necessary to rotate the bezel on the desired hour.

First Rolex GMT-MASTER - 6542

The first Rolex GMT-Master was introduced around 1954. It is first released with reference number 6542, and the movement could indicate the exact time simultaneously in 2 different time zones. With a 38 mm diameter, it was originally manufactured with a blue and red bakelite bezel, which is later replaced with a blue and red metal bezel.


In 1959, the GMT-Master with reference number 1675 is produced. Rolex modified the case diameter to a larger 40 millimeters. With the larger diameter, it becomes easier for the wearer to read the time. Additionally, Rolex added crown guards on the case to protect the crown from getting damage.

The GMT-Master 1675 was first produced with glossy gilt dial. However in the late 1960s, the dial was changed to a matte dial.

This watch is in production for 20 years, so the dials has changed many times, resulting in many different markings version of the dial.

This model is also available in 18 ct gold, also super popular until today among watch collectors. In 1971, Rolex creates the GMT-Master in stainless steel and yellow gold with reference number 1675. It is offered with either an Oyster bracelet or with a Jubilee bracelet, both in Rolesor, which means a combination of stainless steel and gold.


In 1979, Rolex launches the GMT-MASTER in stainless steel with reference number 16750. This watch comes with the quick date change feature. This updated feature helps a lot with changing the date, because before, we need to turn the crown for two full rotations to change the date. The watch is updated with two lock position at the crown. Now, we can easily set the date.

This release also added a new black color bezel to match with the black dial. For people who wanted a monochrom watch, they could opt for the black dial & black bezel GMT-Master. This watch is extremely rare.

Rolex also released the steel & gold model with reference number 16753, and the 18 ct gold model with reference number 16758.

One quick note is this model will be the final GMT-Master with acrylic crystal.


Rolex introduced us to the concept of an independent hour hand for a GMT-Master in 1983 with the release of a GMT-Master reference number 16760 which allows the wearer to know the time in 3 different time zones. Also known as the “Fat Lady”, it is po wered by a different type of movement, the 3085 movement.

With previous generations of the GMT-MASTER, the two hour hands were linked directly to each other, meaning they couldn’t be set separately. This new movement allowed the center hour hand to be set independently from the arrow-tipped 24-hour hand.

This watch also marks the shift of using sapphire crystal in replacement of the use of acrylic crystal. The sapphire crystal makes the GMT-MASTER scratch resistant. The iconic Cyclops at 3 o’clock remained to magnify the date window.

16700 & 16710

Completing the transition from GMT-MASTER to GMT-MASTER II, Rolex released 2 models in 1989: one for GMT-MASTER, and the other for GMT-MASTER II.

Both models feature a black color matte dial, with the use of 18k white gold around the luminous hour-markers. This was done to prevent tarnishing on the dial so that the dial can be preserved for as long as possible.

The bezels came in three diversity: Black, Black & Red, and Blue & Red. The two colored dial has been the hallmark of the GMT-MASTER since its introduction as they illustrate the day apart from the night. This was also the first time Rolex adopt the black and red color combination on the bi-directional bezel, and it quickly gained the nickname “Coke”, perfectly integrating itself with the other “soft-drink” bezels like “Pepsi” and “Root Beer”.

The final model for GMT-MASTER, bears the reference number 16700. The watch comes in stainless steel case, and for the bracelet, a buyer can choose to have either an oyster or jubilee bracelet. Offered at a lower cost alternative at that period, it looks nearly identical to the GMT-Master 16710. However, it resembles the original concept of GMT-MASTER. It comes with black bezel or the blue & red “pepsi” bezel.

We may encounter this watch with a “Coke” bezel. This bezel is obtainable from its cousin, the GMT-Master II 16710, who share the same bezel.

Meanwhile, the GMT-MASTER II came out with a full collection of the different materials. stainless steel watches (with reference number 16710), also Rolesor yellow gold and steel watches (with reference number 16713) and the full gold watches (with reference number 16718). They may also bear the reference number 16710T, 16713T and 16718T respectively. T stands for the French Trou (hole), which means it has a blind hole and the springbar cannot pierce through the holes.

The stainless steel 16710 comes with 3 different bezel colors: All Black, Blue & Red (Pepsi), or Black & Red (Coke).

The gold and steel combination watch 16713 comes with 2 different bezel colors: Black whose dial is also black, or Gold and Bronze bezel whose dial is brown. The Gold and Bronze version would famously be known as the “Root Beer”.

This is the final GMT-Master watches with Aluminium bezels. Rolex will change the material of the bezel insert to ceramic. When people talk about vintage Rolex Pepsi, the watches that we seen are considered vintage nowadays. The vintage watches are light and easy to wear on the hands, so it makes them very popular nowadays.

We have come to the end of our blog. Hopefully, you enjoy today's blog.
