I have never owned a Baume & Mercier until now. I have kept up with their latest offerings but had never really looked into their back catalog. Recently, I came across the Capeland Ref. 65726, re-launched in 2011, and realized that the B&M watches I liked most were not the current designs but the ones buried a few years back. While digging into their older designs, I stumbled across the Hampton Square (Ref. M0A08749), which appeared around 2013-2014. I found a great deal on one, and after it landed in the mail, I was pleasantly surprised.
If the Cartier Santos and the Rolex Yacht-Master 42 had a child, it might look something like this. Square watches of this size often come across as dainty, but the Hampton Square feels like an armored tank. At the same time, it is still elegant enough to wear as a dress watch.
Case and design
The case is stainless steel with an outer frame of DLC-coated steel, locked down with visible screws that look like Allen sockets. It makes the watch look more industrial than refined, though that works in its favor. It is not pretending to be delicate. The profile is bold, and on the wrist it feels secure, heavy, and overbuilt.
At the back, Baume & Mercier gave it a partial display caseback. You can only see a slice of the movement through a window, but it gives the impression of depth and adds curiosity. Getting the caseback off looks like a job for a watchmaker, not a casual owner.
The oversized crown continues the tool-watch vibe. It is ridged and rough edged to allow for a solid grip. This is not a crown you will struggle with when adjusting the time zones or the date.
Dial and hands
This reference comes with a balanced dual-time display, with the second time zone placed at 6 o'clock. The date wheel has clean action and lines up perfectly with its window. Too many watches have misaligned dates, but this one snaps into position with confidence. The main dial layout is symmetrical and legible, with a refined set of hands that contrast well against the dial.
Movement
Inside the M0A08749 is an automatic ETA 2893-2, modified for the dual-time display. This is a proven, reliable caliber widely used across Swiss brands for GMT watches. It beats at 28,800 vph and carries a 42-hour power reserve. While not in-house, it is robust and serviceable anywhere.
Strap and clasp
The rubber strap surprised me. It is almost as comfortable as Rolex's Oysterflex and integrates well into the butterfly clasp. The clasp itself feels secure and smooth in operation. The only design oddity is how the springbar connection looks when opened. It gives the impression of being precarious, though it has held firm.
One major drawback is that many Baume & Mercier watches, including the Hampton Square, use staked bars instead of spring bars. This creates a few problems: 1) you cannot change the strap on your own, 2) the bars usually have to be destroyed in order to remove them, and 3) even if you manage to get them out, you will need the tools and skill to press in new staked bars. In other words, this is not a job for amateurs. While the strap itself is excellent, the bars do not appear to be stainless steel and are prone to rust. That is not a smart design choice by Baume & Mercier.
On the wrist
The watch wears like a tank but does not feel awkward. The squared shape gives it wrist presence, while the rubber strap and butterfly clasp keep it balanced and comfortable for long wear. It feels modern, sporty, and industrial - but with enough polish to pass as a dress piece if needed.
Brand context and history
Baume & Mercier has been around since 1830, founded in Les Bois, Switzerland. In the 20th century, they became known for elegant but accessible Swiss watches. In 1988, they joined the Richemont Group, which gave them resources but also placed them alongside heavyweights like Cartier, Jaeger-LeCoultre, and Panerai.
The Hampton line first appeared in the 1990s, inspired by Art Deco geometry and rectangular forms. Over the years, Baume & Mercier has shifted the Hampton design language closer to the Cartier Tank or Americaine, leaving behind the squared sport-luxury look of the M0A08749.
In contrast, today's catalog leans heavily on the Riviera integrated-bracelet sports watch, alongside classic round pieces. While the Riviera uses movements like the Valjoux 7753, Baume & Mercier rarely promotes the caliber details - perhaps because they are not in-house. Compared to brands like Longines or Frederique Constant, Baume & Mercier sometimes feels like it is playing it safe rather than taking bold risks. Watches like the Hampton Square show what the brand is capable of when it pushes out something less obvious.
Valuation
The Baume & Mercier Hampton Square Ref. M0A08749 originally retailed in the mid-$3,000 range. On the secondary market, examples can be found between $1,200 and $1,800 in very good condition with box and papers. For a Swiss dual-time with unique case design, that is solid value. Compared to Cartier or even Longines Heritage pieces, this Hampton Square gives you a lot of watch for the money if you enjoy its armored, square aesthetic.
Final thoughts
I came into Baume & Mercier without expectations and came away impressed. The Hampton Square Ref. M0A08749 is not a watch for everyone. Its squared case, industrial screws, and DLC details set it apart from mainstream offerings. Yet, that is exactly why it works.
Baume & Mercier has plenty of history to draw from, but the modern catalog plays it safe. If more of their releases took risks like the Hampton Square, we might be talking about them in the same breath as brands with stronger identities. For now, this watch feels like a find from the archives - one of those pieces that shows Baume & Mercier once made bold moves, and sometimes, those are the most rewarding pieces to discover.
