Speaking of Rolex GMT-Master, veteran players all know that this watch has the most tricks. Coke rings, Inter Milan rings, Sprite rings, preserved egg rings, root beer rings…the variety is so dazzling. But the most popular ones are the Coke Circle and Inter Milan Circle.
Recently, many watch friends have asked purewatches: How to choose between the five-bead chain Coke ring and the plate Inter ring from VS factory? Today we will not deal with the fictitious, but directly compare the two watches together. From the bezel, movement, strap to the wearing feeling, we will explain it clearly to you.
1. Differences in ring mouth: UV discoloration is only found in cola rings
Let’s talk about the core difference first: circle mouth.
The red and blue color of the Coke ring, VS factory uses the V3 version of the latest ceramic ring, the biggest highlight isUV discoloration function. When you shine it with an ultraviolet lamp, the blue area will turn red as a whole, just like the Swiss original. Turn off the UV rays and the color returns to normal. This black technology is not available in the Inter Milan circle.
Although the black and blue color scheme of the Inter Milan circle is classic, it will not change color. If you are after the fun of “playing with watches”, the Coke circle is definitely more interesting.
Of course, the bezels of both watches are made of ceramic, which is highly hard and wear-resistant, so you don’t have to worry about scratches for daily wear. The scales are fully filled and the edges are clear, and neither company is lazy in this regard.
2. GMT pointer: red needle vs blue needle, identify your identity at a glance
Another obvious difference is the GMT hand.
Coke rings are usedRed GMT needle, the Inter Milan circle usesBlue GMT needle. This color matching logic is exactly the same as the original one, with red against the red and blue circles and blue against the black and blue circles, perfecting the visual coordination.
The hands are polished very finely, the edges are rounded and burr-free, and the luminous filling is even. The ice blue luminous effect matches the original version, making it clear and non-glaring when reading at night.
3. Movement core: Dandong 3285, stability is king
As for the movement, both watches are equipped with the Dandong 3285 integrated movement, which is currently the most stable 3285 version in the replica circle.
Why must you choose Dandong 3285? purewatches will tell you three points:
- Power reserve 72 hours: If you take it off on Friday and put it on on Monday, you can still run normally without frequent adjustments;
- Calendar jump function: The calendar jump at midnight is crisp and smooth, without any sloppiness;
- Strong stability: The repair rate is low, the travel time error is controlled within ±5 seconds, and it is worry-free for daily wear.
Some small manufacturers on the market use the 2836 movement to fool around. Although it can keep time, the functional linkage and stability are significantly different from the 3285. Therefore, when buying Greenwich, you must look for Dandong 3285. This is not negotiable.
4. Watch strap selection: five-bead chain vs plate strap, there is a difference in comfort
The strap is another major difference between the two watches.
Five-bead chain (standard with cola ring): The links are thinner and fit the wrist more comfortably when worn. Especially when you sweat in the summer, the five-bead chain has better breathability and will not make you feel stuffy. But the weight will be slightly lighter.
Plate and strip (standard for Inter Milan circle): The chain links are thicker, the overall weight is heavier, and the “pressure feeling” when worn on the hand is stronger. If you like a heavy texture, strips are more suitable. However, the comfort is slightly less than that of a five-bead chain, especially those with thin wrists may find it a bit awkward.
A little reminder: the Coke ring can also be equipped with a plate strap, and the Inter Milan ring can also be equipped with a five-bead chain, depending on personal preference. But purewatches’ suggestion is: a Coke ring with a five-bead chain is more classic, and an Inter Milan ring with a plate strap is more sporty.
5. Disk details: solid central axis + blue film bubble mirror, quality online
As for the dial, the workmanship of both watches is very solid.
The bottom bracket adopts a solid design with only a little bit of hollowness, which is much stronger than the obvious hollowness of the previous C factory. The hands are finely polished, with no burrs on the edges, and the second hand moves smoothly.
The three o’clock calendar window is equipped with a bubble mirror, which is coated with blue film. The magnification effect is clear, the font is centered and full, and there is no skew or blur. VS Factory has always done a good job in this regard, and the details are in place.
The logo on the dial is clearly printed, the fonts are evenly spaced, and you can’t find any faults even at a close distance. The luminous fill is full and the ice blue tone is consistent with the original version, making it very convenient for reading at night.
6. Material and weight: 904 steel + ceramic ring, the texture is not timid
The cases of both watches are made of 904L fine steel, which is corrosion-resistant and wear-resistant, and will not easily turn black and oxidize after long-term wear. This is much more reliable than 316L steel.
The ceramic ring has high hardness and leaves almost no traces from daily key friction or table bumps. The scales are filled with platinum powder, which will not fade or fall off after long-term wear, and is extremely durable.
In terms of weight, the plate and strap model is definitely heavier than the five-bead chain because the metal density is higher. If you like a tight feel, choose a strap; if you are looking for lightness and comfort, choose a five-bead chain.
