Citizen Adds Two Compact Field Watches to Eco-Drive Lineup with 40 mm Cases

Citizen's latest additions to its Eco-Drive collection move away from the larger aviation chronographs we've seen recently, focusing instead on the classic field watch archetype. The new AW1870-08A and AW1877-09X, announced by Citizen Spain, are designed with a clear priority on legibility and durable construction, stripping away complications to deliver a pure time-telling experience.

What's New: A Return to Compact Proportions

The most significant change from recent Citizen releases is the case size. Both new references feature a 40 mm case diameter with a thickness of 10.4 mm. This represents a deliberate step back from the larger 43 mm cases found on Citizen's recent aviation chronographs, aligning more closely with the traditional dimensions of military field watches from the mid-20th century. The smaller profile offers a more versatile fit for a wider range of wrist sizes and maintains the historical authenticity that enthusiasts often seek in a field watch design.

The two models offer distinct visual identities:

• AW1870-08A (Classic Field): This reference features a silver-tone stainless steel case paired with a matte white dial. The dial uses bold black Arabic numerals for maximum clarity, with a red minute track providing additional color contrast. The hour and minute hands are black, treated with a luminous coating to ensure visibility in low-light conditions. It's paired with a heavy-duty green nylon strap with a traditional buckle closure.
• AW1877-09X (Stealth Field): For a more contemporary look, this model utilizes a grey PVD-coated steel case and a textured olive green dial. The color scheme is more subdued, giving it a "stealth" aesthetic while maintaining the same functional layout. It also comes on a matching green nylon strap.

The Engine: Caliber J810 Eco-Drive

Powering both watches is Citizen's Caliber J810 Eco-Drive movement. This is a quartz movement that generates power from any light source—natural or artificial—eliminating the need for battery replacements. On a full charge, it maintains an 8-month power reserve. The movement includes a simple date window at the 3 o'clock position, a common and practical complication for daily wear.

Trade-offs and Practical Considerations

While the watches are built for durability, there are notable trade-offs. Citizen specifies a 10-bar (100-meter) water resistance rating and a threaded screw-down case back, which is respectable for a field watch and suitable for swimming and snorkeling. However, the crystal is mineral glass rather than sapphire. Sapphire is significantly more scratch-resistant than mineral glass, which is more prone to scuffs and scratches from daily wear. For a tool watch intended for active use, the choice of mineral glass is a practical cost-saving measure that some potential buyers might find disappointing, especially at this price point.

Pricing and Availability

The new models are currently listed for the Spanish market through retailer Joyeria Pato. Pricing is as follows:

• Citizen AW1870-08A: €143.10 (approximately $169.45 USD)
• Citizen AW1877-09X: €152.10 (approximately $180.10 USD)

The grey PVD variant carries a slight premium, likely due to the coating process. These prices position the watches as accessible entry points into the Eco-Drive ecosystem with a classic field watch design.

Who It's For

These watches are best suited for buyers seeking a no-nonsense, durable timepiece with a historical aesthetic. The 40 mm case makes them a good option for those who find modern watches too large. The Eco-Drive technology appeals to those who want a low-maintenance watch without the hassle of battery changes. However, buyers who prioritize scratch resistance and premium materials might want to consider models with sapphire crystals, even if they come at a higher cost.
