A black and orange chronograph, a tachymeter bezel, and no need to spend €6,000: that is the promise of a Seiko mod Speedmaster. In this guide, you will see what this watch is really worth, what it costs, how it differs from the original and which model to pick. We have assembled more than 500 watches assembled and delivered from our French workshop, and our customers rate us 5 out of 5 stars across 50 customer reviews published on the site.
A Seiko mod Speedmaster is a chronograph watch inspired by the Omega Speedmaster, built from Seiko components: steel case, sapphire crystal, tachymeter bezel. At Time2Seiko, it costs €289, it is hand assembled in France and covered by a 2-year warranty. It is not a counterfeit: no Omega logo, an openly custom creation.
What is a Seiko mod Speedmaster?
The idea is simple. We start from a genuine Seiko movement (the "engine" of the watch), then dress it with a case, a dial and a bezel in the spirit of racing and exploration chronographs. Every part is chosen, assembled and adjusted in our French workshop. The result looks like a legend, without borrowing its name.
At Time2Seiko, this spirit comes in two families. The SEIKOSPEED takes the black dial and orange accents. The SEIKOMASTER plays the three-register chronograph and tachymeter card (the graduated scale used to calculate an average speed). Three traits almost always come back:
- A high-contrast black dial, readable at a glance.
- A tachymeter bezel, the signature of racing watches.
- A sapphire crystal (the hardest material after diamond), so almost scratch proof.
When I put a SEIKOSPEED next to a photo of the original, the difference is obvious. Our watch carries the Time2Seiko name, with no Omega logo at all. It draws inspiration, it does not pass itself off as the original.
SEIKOSPEED or SEIKOMASTER: which model to choose?
For a Seiko mod Speedmaster, both ranges are priced at €289, with the same warranty. The choice comes down to look, size and movement type. Here are the most requested models:
| Model | Style | Case | Strap |
|---|---|---|---|
| SEIKOSPEED black & orange | Black dial, orange accents | 904L steel, 42 mm | Steel |
| SEIKOMASTER speed black | Understated black chronograph | 904L steel, 41 mm | Steel |
| SEIKOMASTER speed snoopy blue | Blue dial, contrasting registers | 904L steel, 41 mm | Rubber |
| SEIKOSPEED fuji redline | Black and red, racing spirit | 904L steel, about 40 mm | Grey NATO |
My advice for choosing your Seiko mod Speedmaster: if you hesitate, start from the contrast. Black and orange catches the eye and stands out on the wrist. Pure black goes everywhere, from the office to the weekend. Blue adds a more relaxed touch.

Movement, sapphire and reliability: what is really inside
It is the number one fear: "will a modified watch last over time?" Let us be concrete. On the chronographs of the range, we often use the Seiko VK63 movement, a mecha-quartz (the time comes from a quartz oscillator, the chronograph is mechanical). You get quartz accuracy and pushers with an instant return to zero. The other models receive an automatic movement, from the family of the NH35 movement that powers a large part of our watches. Always check the product page: the movement is stated there.
| Criterion | VK63 mecha-quartz | Automatic (NH35 type) |
|---|---|---|
| Accuracy | Very high (quartz) | Good, a few seconds per day |
| Chronograph | Yes, three registers | Depends on the model |
| Maintenance | Battery every 2 to 3 years | No battery, wound by wrist motion |
Before shipping, every watch goes through a workshop quality test: adjustment, pusher check, accuracy verification. And the 2-year warranty covers the movement, the finishing and the components. If something is wrong, we repair or replace it.
During a workshop check, I took a pusher apart to verify the return to zero: the hand snaps back in one go, with no play. This kind of detail is what separates a real watch from a simple decorative object.
A word on water, let us be frank. A chronograph with pushers is not a dive watch. It withstands splashes and rain. For more frequent contact with water, a reinforced 5 ATM option exists on these models.
How much does a Seiko mod Speedmaster cost?
At Time2Seiko, the price of a Seiko mod Speedmaster is €289, whatever the colour you choose. To put the gap in perspective, here is the comparison with the original:
| Criterion | Original Speedmaster | Time2Seiko Seiko mod |
|---|---|---|
| Price | €6,000 and up | €289 |
| Assembly | Swiss manufacture | French workshop, by hand |
| Crystal | Depends on the reference | Sapphire |
| Customisation | No | Dial, strap, engraving |
| Warranty | Depends on the retailer | 2 years, human support |
Why not €150 like some listings? Because those watches often arrive from Asia in a sealed box, with no inspection. With us, someone opens it, assembles, adjusts and tests. That work has an honest cost, and it explains why our customers post 5 star reviews on time2seiko.fr.
Which watch size for your wrist?
A Seiko mod Speedmaster wears rather large: the SEIKOSPEED black & orange is 42 mm, the SEIKOMASTER models 41 mm. On a chronograph, size is felt more than on a classic watch, because the dial carries three registers and a tachymeter. A quick check helps: measure the width of your wrist, then compare it with the case diameter.
- Wrist of 16 to 17 cm: a 40 to 41 mm fits perfectly.
- Wrist of 17 to 19 cm: the 42 mm sits comfortably.
- Above 19 cm: the 42 mm even looks discreet.
One last detail: the lug to lug distance (the span between the two strap attachments) matters as much as the diameter. An adjustable steel bracelet, delivered with a sizing kit, lets you fit the watch without a trip to the watchmaker. To go further, our guide to Seiko mod size for your wrist covers each case.
Legal, reliable, where to buy in France?
Yes, a Seiko mod Speedmaster is legal. An inspired watch is not a counterfeit as long as it copies neither the name nor the logo of the brand. With us, no Omega logo appears, and the mention "custom creation Time2Seiko, not affiliated with the Seiko brand" appears on every product page.
To buy without stress, check these points with any seller:
- A shipment from France, not from a distant warehouse.
- A reachable human customer service, not a chatbot.
- A written 2-year warranty on the movement, the finishing and the components.
- Verifiable reviews: we display 5 out of 5 stars across 50 customer reviews published on the site.
Delivery takes about 2 weeks, the time to assemble and test your watch. If you like the chronograph style but hesitate with another tribute, our Seiko mod Daytona guide compares the same type of movement.
Frequently asked questions
What is a Seiko mod Speedmaster and how does it differ from the original?
It is a chronograph watch inspired by the Speedmaster, built with Seiko components. It carries neither the name nor the logo of Omega. The difference lies in the price (€289 against €6,000 and up), the assembly in a French workshop and the possibility of customising the dial and strap.

Is it legal and is it a counterfeit?

Which model should I choose between SEIKOSPEED and SEIKOMASTER, and what size for my wrist?
For a bold black and orange look, take the SEIKOSPEED (42 mm). For a more understated chronograph, the SEIKOMASTER (41 mm). If your wrist is under 17 cm, favour 40 to 41 mm. Above that, the 42 mm sits comfortably.
