Casio Tests US Market Interest for MTP-B185 Square Metal Watches Through Experimental Lab Program

Casio appears poised to expand its signature square watch design philosophy to the US market with the potential release of its premium MTP-B185 series. Currently featured in Casio's experimental 'Casio Labs' program on its US website, six distinct models are undergoing consumer evaluation before any official launch decision. This approach represents a strategic shift for Casio, leveraging direct customer feedback to determine which models will make the transatlantic journey.

The MTP-B185 series, originally launched internationally in May 2025, features a distinctive square case design measuring 40mm wide, 32.5mm tall, and a remarkably slim 7.3mm profile. Constructed entirely from stainless steel, these watches feature three-hand analog movements with date complications. The series includes three distinct finishes: silver-toned stainless steel (MTP-B185D series), gold ion plating (MTP-B185G-9A), and black ion plating (MTP-B185B-7A). All variants maintain Casio's reputation for practicality with 50-meter water resistance and approximately three years of battery life from the SR920SW cell.

Casio Labs presents six specific models for US consideration:

• MTP-B185D-1A: Silver case with black dial
• MTP-B185D-7A: All-silver monochrome design
• MTP-B185D-2A1: Dark blue dial with silver case
• MTP-B185D-2A2: Light blue dial with silver case
• MTP-B185B-7A: Black ion-plated case with silver dial
• MTP-B185G-9A: Gold ion-plated case with gold dial

This curated selection offers broader design variation than typically seen in Casio's square watch lineup. The color options range from conservative monochromes to striking two-tone combinations, with the light blue (MTP-B185D-2A2) and black ion-plated (MTP-B185B-7A) models providing particularly distinctive aesthetics compared to Casio's traditional silver and gold offerings.

Compared to Casio's existing square models like the classic A158W or more recent LTP-V005, the MTP-B185 series represents a significant materials upgrade. Where those models use resin cases with mineral glass, the B185's full stainless steel construction paired with its adjustable metal clasp positions it as a more premium offering. The 7.3mm thickness is notably slimmer than many competitors in the metal-cased analog category, including Timex's Marlin series (12mm+) or Seiko's Essentials line (10mm+), giving it an advantage for those seeking low-profile wearability.

The Casio Labs program requires participants to complete surveys and vote for preferred models in exchange for early purchase opportunities. This approach differs significantly from Casio's traditional regional release strategy and suggests the company is carefully evaluating demand before committing to US distribution. While UK consumers have had access to select models since late 2025, no official timeline exists for US availability. Pricing remains undisclosed, though international models typically retail between $99-$149 USD, positioning these as premium options within Casio's analog range.

These watches target enthusiasts seeking Casio's signature durability in a more refined package. The stainless steel construction elevates them beyond entry-level digital models, while maintaining the brand's practical advantages like water resistance and long battery life. They compete directly with Timex's Marlin 34mm and Seiko's SUP880, offering Casio's distinctive square silhouette as a design alternative to traditional round watches. For collectors and everyday wearers alike, the MTP-B185 series bridges the gap between Casio's utilitarian heritage and contemporary metal watch aesthetics.

Casio hasn't confirmed which models will ultimately reach US retailers or when they might arrive. The company states that voter participation will directly influence these decisions. Interested consumers should monitor Casio's US website for updates on the Lab Showcase #1 program and potential purchase opportunities.
