Mondaine Classic Big Date Ladies (Ref. A669.30008.11SBO) Hands-On Review Hands-on Review / Ladies watch / Quartz watches / Swiss Watches

Being a great fan of the Bauhaus approach to industrial design, I always liked the beautiful in its simplicity layout of the famous Swiss Railway Clock and its numerous more compact reincarnations currently sold by the Swiss watchmaker Mondaine. Thanks to the guys from the U.S.-based online retailer, I finally have a pleasure to review one of the recent additions to the growing family: the simple, yet elegant Mondaine Classic Big Date (Ref. A669.30008.11SBO) quartz ladies watch.

Like many local watchmakers, the Swiss-based brand Mondain has a history behind its iconic “Official Swiss Railway Watch” family.

You see, the timekeeper’s simple, efficient, highly-legible design was inspired by the legendary Swiss Railway Clock that was designed almost 70 years ago by a Swiss Federal Railways (Schweizerische Bundesbahnen, SBB) employee Mr. Hans Hilfiker. Besides the laconic, readily recognizable layout of the dial that features clean, bold lines of black and red color that look especially contrast on the bright white background, the clock also featured the signature “Stop to Go” functionality.

Right after reaching 58 seconds, the red seconds hand instantly jumped to 12 o’clock and stayed there waiting for an electrical impulse that was automatically released by the central control system and simultaneously reached all clocks on all SBB stations, thus achieving perfect synchronization of the entire railway system. In a sense, the system designed by Mr. Hilfker anticipated modern radio time signal stations that wirelessly broadcast correct time for millions of radio clocks throughout the world.

Almost instantly after the electric clock was introduced, it became a living classic of Bauhaus design and also an unofficial symbol of Swiss Railways.

Almost twenty six years ago, in 1986, the Swiss watchmaker Mondaine Group (a conglomerate that was established in 1951 and now encompasses such well-known brands as Mondaine Watch Ltd., Luminox and Camel Active) reached an exclusive license agreement with Swiss Federal Railway and officially licensed the design of the clock’s dial, the “Stop to Go” functionality, as well as the right to use the famous SBB CFF FFS logo on the timekeeper’s face.

Since then, the wrist watches enjoy steadily growing popularity among watch enthusiasts.


For this hands-on review I chose one a fairly recently introduced Mondaine Classic Big Date ladies watch (Ref. A669.30008.11SBO) that adds to the simple three-hand design nicely executed Big Date functionality.

The watch comes in a mid-sized, circular-shaped case 30 millimeters in diameter. Crafted from polished stainless steel and sporting a very thin bezel, the body of the watch is as simple as it could possibly get.

Although I have heard people saying that the design of the case is too simple, I would argue that it was the only way to match the understated elegance of the dial that comes with no decor whatsoever. On the other hand, the decision to make the piece as a simple as it was practically possible slightly reduced the usability of the watch: its setting crown, which is, too, crafted from polished steel, is so smooth that it makes it somewhat difficult to operate the watch.

I was also a little confused while setting the big date indicator. While the owner’s manual clearly indicates that the crown must be turned counter-clockwise to change the date reading, I had to do quite the opposite. Or, perhaps it was the pictogram that was too difficult for me to understand.

Otherwise, the timekeeper leaves an impression of unexpectedly high build quality (at least, for the price of $175.00 that it is currently offered at and attention to details. Well, perhaps the black genuine leather strap was a tad too tough to my, ahem, taste, but you can’t expect to get a Hermes strap in this range, can you?

According to official specs, the A669.30008.11SBO is powered by a simple Ronda 509 quartz movement. Featuring only one jewel, the caliber is nevertheless quite popular among Swiss watchmaking brands thanks to its reparability and energy efficiency (the movement will run for 45 months on a standard cell.) It is also quite accurate gaining or losing around no more than 20 or 10 seconds per month respectively.

The only thing that you won’t like about this caliber is the way the calendar is changed: being a “Big Date” movement, it features two calendar wheels instead of one meaning that you will have to change date manually every damn months clicking through all 10 digits on the second wheel. Add into account the mirror-polished setting crown and the task becomes quite annoying rather fast.

I asked my wife to wear this watch for a small photo session and she says that the watch is quite comfortable on the wrist. She was also quite pleased with its thinness, light weight and easily readable dial.

She promised me to wear this timekeeper at least two days per week, so I hope to come update this review closer to the end of the year to tell you how the timepiece fared. Yes, the watch is cheap, but looks more expensive than it is. If you search for a Bauhaus timekeeper, you probably should look no further.
