Heimdallr watches review: are they any good?
Last reviewed 28 September 2026.
Short answer: yes, for Seiko-style divers, but check the movement first. Heimdallr makes SKX007, 62MAS, Tuna and Turtle styles with sapphire crystals and 200m or 300m ratings. Per its own store, 32 of 35 Heimdallr-branded watch listings name a Chinese Hangzhou 2553A or 2565A automatic, read on 28 September 2026. The Amazon listings below name a Seiko NH35A or NH36A. Each was opened on Amazon US that day, with its seller and stock read from the buy box.
What Heimdallr is
Heimdallr is a dive-watch brand that sells direct from heimdallrwatch.com, which ships from China, and on Amazon. Its store is also a shop for sister labels. Of the 69 watch listings on it, 22 are Thorn and the rest include Tactical Frog, Rdunae and KEASO. The same houses turn up at Watchdives. Unlike most houses on this site, Heimdallr names its inspirations outright: its titles and tags say SKX007, 62MAS, 6105 Turtle, Tuna Can, Monster and Sub. Those are mostly Seiko originals, which this database does not rank yet, so no Heimdallr watch has a fidelity score here.
The movements: which one you get depends on where you buy
- Hangzhou 2553A: named on the store's SKX007 Applied V2, SKX007 NH36, SKX007 V 2K20, Monster and Turtle listings. The title of the store's “SKX007 NH36” listing names a Seiko calibre while its spec block names a Hangzhou one. That is the clearest example of why the spec block, not the title, is the thing to read.
- Hangzhou 2565A: named on the Titanium SKX007, the Tuna Can and the 62MAS listings.
- Seiko NH35A / NH36A: named on the store's SKX007 Marine300 (NH35A, sold out on 28 September 2026). The Full Lume SKX007 V2's spec block names both a Hangzhou 2565A and a Seiko NH36A. All three Amazon listings below name a Seiko calibre.
Both families are automatics. The Seiko calibres are the more widely known and serviced. If that matters to you, buy a listing that names one.
Three Heimdallr watches on Amazon
- SKX007 (model HMD-007): the brand's core watch. 42mm × 13mm steel case, NH36A automatic, black ceramic bezel, wave dial, sapphire with inner anti-reflective coating, 200m, on a 22mm steel bracelet, all per the listing. Listed under the Tactical Frog brand. Sold by TACTICAL FROG Watch and shipped by Amazon, in stock on 28 September 2026. Amazon ↗
- Titanium diver (model SD-HDM-T007): the same idea in titanium. 42mm × 13mm, NH35A automatic, sapphire, 200m, titanium bracelet, 125g per the listing. The titanium SKX007 on Heimdallr's own store lists a Hangzhou 2565A and 44.3mm including the crown, so the Amazon version is not simply the same watch. Sold by TACTICAL FROG Watch and shipped by Amazon, in stock on 28 September 2026. Amazon ↗
- HMDH15: a Heimdallr-branded diver sold by the brand itself. 43mm steel, NH35A automatic, ceramic bezel, sapphire, screw-down crown and case back, 200m, per the listing. It does not appear on Heimdallr's own store. Sold and shipped by HEIMDALLR WATCH, in stock on 28 September 2026. Amazon ↗
Other listings carry Heimdallr in the title, many sold by a third seller, Lurcan. We link the three whose model number and movement we could read on the listing, from a seller tied to the brand.
FAQ
Are Heimdallr watches any good?
Yes, for Seiko-style divers. Heimdallr builds SKX007, 62MAS, Tuna and Turtle styles in steel, titanium and bronze with sapphire crystals and 200m or 300m ratings. The thing to check is the movement: on Heimdallr's own store, 32 of its 35 Heimdallr-branded watch listings name a Hangzhou 2553A or 2565A automatic, while the Amazon listings we checked name a Seiko NH35A or NH36A.
What movement does Heimdallr use?
Mostly Chinese Hangzhou automatics on its own store: the 2553A in the SKX007 V2, Monster and Turtle styles, and the 2565A in the Titanium SKX007, Tuna and 62MAS styles. A few listings name Seiko's NH35A or NH36A or a Miyota. On Amazon, the SKX007 we checked lists an NH36A, and the titanium diver and the HMDH15 list an NH35A. Read the movement line on the exact listing.
Is Heimdallr the same as Tactical Frog?
They are sold together. Heimdallr's own store also sells Tactical Frog, Thorn and Rdunae watches. On Amazon, Heimdallr's SKX007 and titanium divers are listed under the Tactical Frog brand and sold by a seller named TACTICAL FROG Watch, with Heimdallr in the listing title.
Which original watches does Heimdallr make homages of?
In its own titles and tags: the Seiko SKX007, 62MAS, 6105 Turtle, Tuna Can and Monster, and the Submariner (as Sub). It names no other Swiss original. None of those Seiko originals has a page in our database yet, so no Heimdallr watch carries a fidelity score here.
