■ Vintage-style gentle design
The EG2790-12A has an attractive design that gives off a vintage atmosphere while also giving a sense of gentleness and calm. The square case with rounded sides gives it a sophisticated and gentle feel.
A perfect balance between classic design and modern sophistication. This is a special piece that combines the warmth of a vintage watch with Citizen's precision technology.
■ Small and delicate square case
The small case size of 17.3mm in width fits beautifully on a woman's delicate wrist. Although the square case has a strong presence, it gives a modest and elegant impression.
The thin design is only 5.4mm thick, so it fits neatly into your cuff. It has an exquisite size that is easy to match with any style, from business to casual.
■ Ultra-lightweight design weighing only 14g
This model is surprisingly light, weighing only 14g. It's so comfortable to wear that you'll forget you're even wearing it. You won't get tired even if you wear it for a long time, making it perfect for everyday use.
Coupled with the small case, it is an ideal design that does not put strain on your arms. The delicateness that does not spoil the delicate impression is attractive.
■ Index unified with Roman numerals
The dial uses indexes that are unified with Roman numerals. It gives a classic and elegant impression and accentuates your calm expression.
The silver Roman numerals look beautiful on the black dial, and visibility is excellent. Feel the classic beauty every time you check the time.
■ High-quality leather band with embossed pattern
The band is made of embossed cowhide leather, giving it an attractive classic feel. The black leather band adds a sense of calm and luxury to the overall design.
The soft feel of a leather band is also a great feature. The more you use it, the more it will fit on your wrist, so you can use it for a long time.
■ Accented with a slightly larger crown
The key point of the design is the placement of a slightly larger crown for the smaller case. This accent adds personality to a simple look.
From a practical standpoint, the large crown is easy to operate and allows you to set the time smoothly. This is an idea that balances design and functionality.
■ Drives for about 8 months with photovoltaic Eco Drive
It is equipped with Citizen's original photovoltaic power generation "Eco-Drive" that converts sunlight and small amounts of indoor light into electricity to keep the clock running. It can run for about 8 months when fully charged, so there is no need to regularly replace the battery.
It also has a charging warning function, overcharging prevention function, and time adjustment notification function, so you can always use it with confidence. It is an environmentally friendly and practical technology.
■ Use of environmentally friendly recycled materials
The dial parts are made from recycled materials, making this watch environmentally friendly. In addition, Eco-Drive, which does not require regular battery replacement, is the first watch to be certified as an Eco Mark Product (environmentally friendly product) by the Japan Environmental Association as a product that protects the global environment.
It can be said to be a watch suitable for modern times, as it combines beauty and environmental friendliness.
■ Waterproof and safe for everyday use
The waterproof design for everyday use allows it to withstand minor exposure to water such as hand washing or rain. Its appeal is that it is highly practical and can be used on a daily basis without hesitation.
■ Adopts crystal glass
The windshield uses highly transparent crystal glass. It allows you to clearly see the beautiful dial.
It has a moderate hardness and protects the dial from minor scratches caused by daily use.

■ Buyer's comment
When I first picked up the EG2790-12A, I was drawn to its small and delicate form. Weighing only 14g, it's surprisingly light and so comfortable you'll forget you're even wearing it. The vintage-style design is very elegant, and the combination of Roman numeral indexes and embossed leather creates a classic atmosphere. The square case has a strong presence but is not too overpowering, and is attractive because it is easy to match with any style. I think it's practical and can be used for a long time, as it can last for about 8 months with Eco Drive. by Fujimuro
