Is my payment information secure?
Our website and payments platform is powered by Shopify, which complies with all six PCI standard categories, making it among the most secure payment platforms on the web.
What is the difference between the Premium Dial and Standard Dial watch?
Despite the name, in reality both of our dials are premium and have identical quality in terms of finishing, lume, and cost. Both dials are constructed of the same high-quality copper.
The only difference is in the face of the dial itself. The Premium option includes a printed logo, and is designed as an homage to the GMT-Master dial. The Standard dial is more understated and minimalist in terms of the amount of text on the face, and includes a metal logo instead of a printed logo.
The Standard dial the only option we carried when our website launched. When we began offering the Premium dial, that moniker was chosen simply as a way to differentiate the watch.
I'm in love with my submariner. It really complements any outfit and is probably the best purchase I have made when it comes to watches. Buying this for a less than $500 vs a Rolex Submariner for over $13k on the gray market... easy choice for me!
Thanks, we totally agree! 95% of the watch for 5% of the price

I have received multiple compliments on this watch, it is well built, has that weight and feel of a quality watch and the movement for the price can not be beat, will buy again!

Really like the look and feel of this watch. Very solid and elegant. 2nd SWC and very pleased. See watch on left

The watch has been perfect I've enjoyed wearing it daily and plan to purchase more in the near future.

I liked the GMT so much that I decided to also buy a Daytona! I own a couple of Rolex watches but really like the quality and finish of these Somerville watches.....not to mention the value!!!!!! They were also very responsive to my questions.

Great watch, looks better than pictures! Runs well, so far! Great service as well. I will recommend your company to others. Keep up the good work!! ABOVE EXPECTATIONS!! THANK YOU, GARY IN OHIO 5 stars for review!!!

Thanks for the great service and quality of my new watch. I am so impressed I have ordered a new GMT watch today.

Just got this in today. It’s my 3rd piece from Somervillle Watch Co.
Really impressed with this watch. The weight, the feel, the look. All better than I expected. This is perfect for my int’l trips when I don’t like taking my ‘real’ luxury timepieces. But also great for a day or night out! This is the epitome of understated elegance.

Really impressed with this watch. The weight, the feel, the look. All better than I expected. This is perfect for my int’l trips when I don’t like taking my ‘real’ luxury timepieces. But also great for a day or night out! Had several unsolicited compliments over a 2 day period.

I’ve been looking for a Mod Sub for sometime now and I’m beyond happy I purchased this watch. The look, feel and detail is amazing as well as the quality of this watch. I’ll being adding a GMT to my collection from Somerville in the near future!

Highly recommend Somerville Watch Co.!! Not only for the excellent quality watches, but also for the perfect customer service experience. Like any other product out there you have choices. Don’t bother taking a chance with a different Seiko mod dealer. Somerville is the only one that I would purchase from. I already have two watches from them and plan to purchase more!!

I purchased this watch as a christmas gift for my boyfriend this year. He loves it, it feels very sturdy and luxe, not to mention beautiful. His wrists are on the smaller side and he liked that this watch is a couple millimeters smaller than a standard speedmaster (according to him). Harman was very helpful and emailed me back very quickly when I asked about the lug size (it’s 20mm) so I could buy another strap to interchange with the metal bracelet that comes with this watch. Shipping was fast and easy! Highly recommend, thank you Harman!

Very pleased with my purchase so far watch looks amazing and is keeping great time!

The pictures don't do these watches justice, it definitely exceeded my expectations. I'm in the process of ordering a second watch with a custom dial as we speak. Not to mention, Harman responds to inquiries super fast. 10/10 would recommend!

The Le Mans mod Seiko is not only a beautiful time piece but Somerville Watch Co. delivers outstanding customer services and white glove service from ordering to walking you through setting up the time piece upon delivery. I recommend this particular watch for its complexity and beauty but also encourage to use Somerville Watch Co. for any watch needs.
