The Timex Giorgio Galli S1 Automatic 38mm is a compact steel automatic with a sapphire crystal and an 18mm strap width. The black model is reference TW2V70300; the Atlantic Blue version is TW2V03500. Timex does not publish the black model’s movement caliber, power reserve or accuracy tolerance on its product page, so buyers should weigh the documented design and dimensions against those unanswered movement questions.

Which Timex Giorgio Galli S1 38mm is this?

Check the reference number as well as the dial color. Timex identifies the black-on-black 38mm model as TW2V70300. The Atlantic Blue model is TW2V03500. Listings, prices and stock status for one reference should not be assumed to apply to the other.

What are the published specifications?

Timex’s EU listing for the black TW2V70300 gives these specifications:

Specification Timex listing
Case diameter 38 mm
Case height 11 mm
Weight 71.82 g
Case Stainless steel, brushed and polished
Crystal Double-domed sapphire
Movement Automatic; caliber not stated
Dial and case color Black
Band/lug width 18 mm
Water resistance 50 m

These are Timex’s published figures for the black reference, not independent measurements. The description calls the strap soft synthetic rubber and notes its riveted strap-keeper design. The brand’s broader S-series retrospective also describes the S1’s custom case, automatic movement, double-domed sapphire and synthetic-rubber strap, but does not identify the 38mm watch’s caliber: Timex’s S-series retrospective.

  • Please be attention that screen protector is flexible plastic film, Not Tempered Glass.

  • 4H Hardness can effectively resist daily scratches.

What does 50 m water resistance mean here?

Timex describes the 50 m rating as suitable for light swimming, but not snorkelling or poolside diving. Treat the brand’s stated use guidance as the practical boundary; the rating is not a promise that the watch is appropriate for every water activity.

What is known—and not known—about the automatic movement?

The official TW2V70300 page confirms that the watch is automatic, but does not state the caliber, power reserve, accuracy tolerance, jewel count or service interval. Those details are therefore not established for this reference by the listing. Do not fill the gaps using specifications for the earlier 41mm S1 or another watch listing unless that information is explicitly tied to TW2V70300.

How did the 38mm version come about?

In a February 15, 2022 article, Esquire described the 38mm S1 as a 3 mm reduction from the original 41mm model. The redesign added sapphire crystal while retaining a $450 launch price, according to that article; that is historical launch context, not a current price. Esquire also reported that balancing the case’s proportions at the smaller size was a significant design challenge. Timex Group chief creative director Giorgio Galli said: “At the end,” Galli says, “it became quite a big project to keep the essence and the philosophy of the S1.” Read the dated coverage at Esquire.

What were the listed prices and stock statuses?

On October 8, 2026, Timex’s EU page for black TW2V70300 displayed €475 and “Out of Stock”; the UK page for Atlantic Blue TW2V03500 displayed £425 and “Low Stock.” These are date-specific observations for different references and regions, not a like-for-like comparison or a guarantee of current availability. Check the relevant local listing before buying.

The UK listing also displayed a Timex-hosted rating of 4.72/5 from 68 customer reviews when accessed in 2026. That is retailer-hosted customer feedback, not an independent performance test or a controlled survey.

What strap fits the black 38mm S1?

Timex lists the black case’s band/lug width as 18 mm. Search for an 18 mm replacement strap, then confirm that its attachment and spring-bar arrangement suit the watch before ordering. Timex separately lists a Galli S1 replacement strap, TW7C82700, as 20 mm wide; the published dimensions do not establish it as compatible with the 18 mm TW2V70300. See the official 20mm strap listing for its stated width.

Is the Timex Giorgio Galli S1 38mm worth buying?

It is a plausible choice if you want a 38mm steel automatic with a double-domed sapphire crystal, a relatively slim stated 11mm case height and a synthetic-rubber strap. The most important caveat for a specification-led buyer is that Timex’s page leaves the movement’s caliber and performance details unspecified. Confirm the exact reference, regional price and stock, and strap fit before deciding; the available sources do not establish an apples-to-apples competitor comparison.
