Frequently asked questions

What is a Mod?

A Mod is a custom, modified watch (hence the name: Mod). Each watch is hand assembled by us.

Our watches begin with a genuine, Japanese movement. We take this movement, and complement it with our own custom-produced dials, hands, cases, and bracelets. The specific movement used is listed in the description for each of our products.

Somerville Watch Company is not affiliated with any other brands. We are an independent watchmaker, and each watch we sell includes a 1-year in-house warranty. Since these watches are custom-made by our company, they will not include a papers.

Why do you use custom parts?

The answer is simple: because there is simply no way to deliver the premium aesthetics and functionality that we strive for when using fully stock watches as a base for our mods.

If you have any doubts about our products whatsoever, reach out to us via email.

What is the difference between a Mod and an OEM Seiko watch?

Somerville Watch Company is an independent watchmaking workshop based in Somerville, MA. Every watch we sell is hand-assembled by us, built from genuine Japanese movements combined with custom-produced components - crafted to deliver an aesthetic you simply won't find off the shelf from an OEM manufacturer like Seiko.

Each of our Mods is a custom creation, carefully inspected and tested before it leaves our hands. We don't cut corners, and we don't dropship. What you get is a watch built for you, backed by our 1-year in-house warranty.

Where are you located, and do you have a physical location?

As our name implies, we are located in Somerville, Massachusetts.

We are an e-commerce only business, with no plans for opening a physical location.

For logistical reasons, we are unable to offer local pick-up from our workshop. We do however offer free shipping to all customers, regardless of their location.

How fast will my watch arrive?

For the most accurate delivery estimates and pricing, add an item to your cart and enter your mailing address at checkout. The checkout page will then populate with real-time pricing and delivery estimates provided by our delivery partners.

Shipments within the U.S. are FREE and arrive within 2-5 business days, depending on your location and distance from Somerville, MA.

been looking into picking up a seiko mod for a while, I live near somerville and chose to support a relatively local business. I could not be happier with it. I will 100% be buying more and recommending to my friends

Great watch

Great watch, is exactly as advertised. It came fast and in nice packaging. The watch face is flawless and the movement has that signature snap back action on the chronograph.

One of our favorites!

Absolutely beautiful watch!

Great watch, easily mistaken for a luxury name brand and half the price of a similar off the shelf Seiko!

Thanks for the review, the watch looks great on you!

Finally, a battery operated Speedmaster

I love this watch. Looks and feels like a high quality Omega Speedmaster but out does the Speedmaster (in my opinion) because it is reasonably priced and has a battery operated movement. Saves me the time and need for manual winding and/or daily wear. As the owner of several watches that I rotate through each day, the conveince of battery operation (although not cool for high end watches) is perfect for practical applications.

Looks amazing!

Handsome watch. Solidly built

Very pleased with this mod adaptation of the “Daniel Craig” Omega Speedmaster. The Seiko quartz movement keeps outstanding time. I own an Omega black dial Speedy. This Somerville-built white dial is even more attractive. Indeed, the white dial is as carefully sculpted as the Omega. And at a fraction of the price. And the band is also excellent
Finally, the 904L steel case and bracelet is Rolex-like.

Thank you for the review, Gerald!

Great Homage Piece

I have a speedmaster that I love but I don’t want to wear it to work. I bought the Seiko Speedmaster and it’s amazing. Fantastic detail, the seconds hand functions flawlessly with a quick snap back to perfect 12 o’clock when reset. I couldn’t be happier, and it’s patrol ready. Been wearing on patrol since I got it. 10 stars if I could rate it that high!

Looks great! Thanks for the review!

Love it!

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). SWC 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 SWC!

Hi Kayla, we are so glad to hear that your boyfriend approves of the watch! You rock at gift giving

LOVE IT!

I am so so so happy with this watch. It feels really premium and it's already been mistaken for an Omega several times. People think it's awesome when I point out it's a Seiko Mod and how I got it from a small business. Keep up the good work!

P.S. I purchased one of these on the Mercari store for Somerville Watch Co. before I knew about their website. My next purchase will definitely be direct through the store, since it is a much better deal when you factor in all of those Mercari fees!

Thanks Todd, the watch looks great!
