How to choose the first formal watch for a newcomer in the workplace? If you have a limited budget and want to wear something classy, Omega Diefei is definitely a name you can’t avoid. The simple and restrained design can be used for commuting, business, and dating. However, the price of more than 20,000 yuan at the counter has made many cousins difficult.
Fortunately, the replica market gives us a “replacement” option. This 39.5mm Butterfly from the MKS factory is equipped with the Miyota 9015 movement. Today Purewatches will put aside the fictitious parameter stacking and talk about the real performance of this watch in vernacular.
1. 39.5mm golden size: wear a shirt without cuffs stuck, so friendly
Let’s talk about the most intuitive advantage first: size.
39.5mm diameter + 10mm thickness, this ratio is really the “golden size” of formal watches. It can be easily controlled by wrists as small as 15cm to thick as 19cm. When wearing a shirt, the watch case will not get stuck in the cuffs, and it will not look bulky when raising your hand to read the time.
The watch case is made of 316L fine steel, and the outer ring, sides, and lugs are all highly polished. The edges are hand-chamfered and polished, making it smooth to the touch and not cutting your hands. The bottom cover adopts vertical brushing process, and the glossy shell body is matched with the brushed back cover. The light and dark levels are almost the same as the original ones, which is much better than the one-piece polishing of many small factories.
The crown is independently molded, the sides are frosted with fine anti-slip tooth patterns, and the Omega horseshoe LOGO is embossed on the top with a clear and three-dimensional appearance. When twisting and adjusting, the damping is even and there will be no embarrassment of slipping or jamming.
The mirror is made of double-layer anti-reflective sapphire crystal glass and has a slightly curved bubble mirror design. The reflection is weak when viewing the disk under strong light, and it basically leaves no traces from daily key friction and table bumps.
2. Disk details: true performance under a magnifying glass
The dial is the soul of a formal watch and the key to distinguishing big manufacturers from small ones.
LOGO and base: The base of the disk is divided into two types: silver gray brushed and pure white track. The brushed texture is fine and even, without the messy scratches common in small factories. The three-dimensional embossed Omega horseshoe LOGO at 12 o’clock has completely matched the curvature and thickness, and the edges are transitionally rounded, eliminating the common problem of flat ink overflow.
Scales and Pointers: The nail scales and Roman numerals adopt the dual process of “fine polishing + rhodium plating”. The surface is bright and not black, and the bottom of the scale fits the disk surface without warping. The edges of the pointers are polished smooth and burr-free, and the rotation of the solid central axis will not scratch the disk surface, which many cheap versions are lazy about.
calendar window: The 3 o’clock trapezoidal calendar window deeply replicates the original shape. The calendar background is pure white, and the digital fonts are regular and centered, without the embarrassment of left and right offset or font deformation. The process of adjusting the calendar is smooth, with no stuck calendar or half-jump. It is much better than the early Seagull movement version.
3. Watch strap selection: Steel straps are good-looking but easy to damage, and the straps need to be worn in to make them comfortable.
This Diefei comes in two configurations: steel belt and cowhide, each with pros and cons:
Steel belt version: The full height of the chain links is treated with a polished surface, the connection gaps are even, and there is no obvious looseness or abnormal sound when shaking. The narrow lugs are designed to fit the wrist in the upper hand without protruding.
But there is a real shortcoming: the fully polished steel surface has poor wear resistance, and it is easy to leave tiny scratches when you touch door frames and tabletops with your hands every day. This is consistent with the common problem of original stainless steel belts. Watch friends who mind scratches recommend the belt model.
The clasp has a matching double-press folding clasp, the inside is frosted, the Omega logo is embossed on the surface, and the internal steel-stamped serial number is complete. The opening and closing are moderately tight and will not pop open automatically. The inner corners are rounded and polished, so it will not irritate the wrist when worn for a long time.
Cowhide leather belt version: The factory comes standard with crocodile pattern embossed calfskin. The leather is hard and will feel slightly stuffy when you first put it on. It will soften and fit after about half a month of use. The stitching is neat and without jumpers, the lug interface fits tightly, and the gap control is very small.
If you pursue higher quality, you can replace it with American crocodile leather later, and the overall business atmosphere will be greatly improved. This is very flexible.
4. Movement core: Miyota 9015, stable but noisy
The movement is the biggest upgrade point of MKS Diefei compared to the Seagull 2892 version on the market.
Abandon the domestic movement with a high failure rate in the early years and replace it with the Japanese Miyota 9015 ultra-thin automatic mechanical movement. I disassemble it separately to discuss the advantages and disadvantages:
Movement advantages：
- Ultra-thin adaptation: The thickness of the movement is only 3.9mm, which perfectly fits the 10mm thin watch case. There is no need to change the case structure. The movement fits well and there will be no problems with the bottom of the drum or the back cover warping;
- Stable walking time: After original factory adjustment, the daily error is stable within ±15 seconds, and the positive and negative errors fluctuate very little; it has a built-in second stop function, and the hands stop immediately when the crown is full, making the time correction more accurate;
- Enough power: 72-hour power reserve, fully sufficient for daily commuting, and will not stop easily if left idle for two days;
- Clear timing: Sequentially adjusted calendar design, pull the first gear to quickly adjust the calendar, and pull the second gear to adjust the hour and minute hands. It is simple to operate, the gears mesh smoothly, and there is little jamming when twisting violently.
Inescapable shortcomings: A common problem with the 9015 movement: the automatic rotor makes too much noise. The “rustling” sound of the automatic winding can be clearly heard when the arm swings greatly and in a quiet environment at night.
Cousins who are sensitive to noise and are used to putting it on the bedside before going to bed need to adapt to this in advance. It is a structural problem of the movement itself and cannot be completely eliminated by the factory. Fortunately, the back cover is designed with a dense bottom, so the movement cannot be seen during daily wear, which to a certain extent conceals the visual perception of the abnormal noise of the automatic rotor.
5. Real advantages and disadvantages, do not brag or discredit them
Advantages:
- 39.5mm standard formal size, thin and light, suitable for most men’s wrists
- A complete set of fine molding for the dial, case, and buckle, and the LOGO, scale, and calendar details are restored online.
- Miyoda 9015 movement has a low failure rate, stable running time, and is more durable than domestic ultra-thin movements.
- Sapphire scratch-resistant mirror, 316 stainless steel body, basic waterproof, daily hand washing, no need to take off the watch when exposed to rain
Disadvantages:
- The steel belt is fully polished and can easily produce fine scratches. If you are looking for traceless wear, choose the belt first.
- There is obvious rustling noise when the automatic rotor of the 9015 movement rotates, which is noticeable in a quiet environment.
- The factory standard cowhide leather is hard and the comfort is average. If you have enough budget, it is recommended to replace the crocodile belt later.
- There is no coaxial shock absorber or anti-magnetic structure. Long-term vigorous exercise and close proximity to strong magnetic fields are prone to time deviation.
6. Purchasing Suggestions: Who is suitable to buy?
If your needs are daily work and business entertainment, you want a low-key and simple ultra-thin three-hand calendar formal watch, and you don’t mind the slight noise of the automatic rotor, this Diefei can fully meet your wearing needs.
The golden size of 39.5mm is not picky, which is also the fundamental reason for its long-term sales. If you have a limited budget and want to experience the quality of Omega, this Diefei from the MKS factory is indeed a reliable “replacement” choice.
Purewatches’ suggestion is: find a reliable channel to get the product. When you get it, first check the three-dimensionality of the logo on the disk, the centering of the calendar font and the smoothness of the movement. If there is no problem with these three points, you can basically wear it with confidence.
